Collection Description

The focus of our collection is on motif postcards from the beginnings of postcard making to the middle of the 20th century. Important thematic focuses are cards with a connection to music, cards on the First and Second World Wars as well as cards with images of women and men. We collect topographical postcards, i.e. the classic picture postcards, especially if they are part of a closed correspondence or a historical collection. For example, we have a set of historical albums created by young women during the First World War, in which they collected the news of their husbands, fathers and relatives from the front. Another set of albums includes the cards of the women in one family from the beginning of the 20th century until the 1970s.

Although our holdings are fully digitised, not all collections and postcards are freely accessible on the internet – partly for legal reasons, but also because they have not yet been catalogued. To offer you an overview of our collection, we present our holdings below:

Collection Prof. Dr. Sabine Giesbrecht

Smaller Collections

Special collections (parts of various collections)

Collection Prof. Dr. Sabine Giesbrecht ⇒

Main focus of the collection: music-related images (song postcards, portraits and images of musicians, musical instruments, venues, dance, music in social context, etc.), propaganda, advertising, gender, local history of Osnabrück
Time span: from the 1890s to about 1945
Size: approx. 21,500 postcards (as of 27th April 2023)
Collection not completed
Indexing: fully digitised, partially indexed, largely unlocked
Original order: Own system of shelfmarks (recorded in the database as “old shelfmarks”)
IDs: In the course of the redesign of the database IDs: os_ub_0000001 to os_ub_0016469 were assigned for the postcard stock available up to that point in the order of the original category system. Postcards added at a later date are recorded upon receipt.
Collection history: Dr. Sabine Giesbrecht, Professor of music history at the University of Osnabrück, began her collection around 1980 with the search for historical illustrations for a textbook project. The collection quickly grew beyond this project and numerous scholarly publications followed, each of which added new aspects to the collection. At first most of the postcards were acquired at flea markets and antique shops. Now the collector buys almost all postcards from online dealers. The collection has also been extended through donations from numerous people (see list of donors). From 2001 onwards, the collection was continuously digitised and put on the internet in cooperation with Prof. Dr. Bernd Enders and the Centre for Digital Teaching at the University of Osnabrück (virtUOS). In 2010 Giesbrecht donated her collection to the University Foundation of Osnabrück. Since then it has been kept in the University of Osnabrück’s library.
Funding: Thanks to a funding initiative by the Sievert Foundation for Science and Culture from 2015 to 2018, the old database was replaced by a new system and greatly expanded. The old scans were replaced by new, high resolution and double-sided reproductions. Currently (2020 to 2022) the Giesbrecht Collection is being indexed in detail and researched by a project funded by the Ministry of Science and Culture of the State of Lower Saxony.

Assel worked together with Georg Jäger on the Goethezeitportal and contributed numerous texts, primarily on the art of the Goethe period. The collection reflects both her work for the portal and her great interest in women’s and gender history of the 20th century. The joint postcard collection of Jutta Assel and Georg Jäger, which forms the basis of the Goethezeitportal, has been located in the Herzogin Anna Amalia Bibliothek, Weimar since 2019.

IDs: Collection not yet digitised and indexed
Collection history: The collection was assembled by collector and researcher Jean Ritsema (Jackson, Mich., USA) and donated to the archive in 2021. It was guided by the collector’s interest in the actors of early fashion and beauty photography. Ritsema identified numerous photo models and photographers and researched their biographies. With her collection, she systematically researched the postcard production of several large publishing houses that specialised in portrait, fashion and star photography.
Literature on the collection: The cards in the collection and many research results on various publishers were incorporated, among other things, into the website on the Ross Verlag initiated by Mark Goffee. Today, this site contains overviews of the production of numerous publishing houses in different countries, mainly compiled by Ritsema. Parts of the Ritsema collection can be viewed in thematically arranged albums on Pinterest.

Collection history: In this category you will find postcards from smaller collections which were handed to Mrs. Giesbrecht as gifts at various times. Mrs. Giesbrecht has included a selection from these gifts in her collection. Which postcards these are can be reconstructed in part by the names of the donors or bequeathers. The postcards deposited here were not included in the collection because they did not meet the criteria (the time frame up to 1945 or the main focus of the collection). Nevertheless, some of the postcards contain very interesting motifs, so that we decided to digitise them also.
Literature on the collection:

Collection Heinz Andrejewski

Main focus of the collection: portrait or autograph postcards of musicians and artists, correspondence with musicians, topographic postcards
Time span: from the 1910s to about 1945, one postcard from the 1970s
Size: 176 postcards
Collection completed
Indexing: fully digitised, fully indexed, fully unlocked
Original order: not reconstructable, the categories of the collection and the order of the postcards were determined by Dietrich Helms based on the order in which the collection was received.
IDs: os_ub_0019699 to os_ub_0019848 and os_ub_0021399 to os_ub_0021424
Collection history: The postcards were collected by the travelling musician Robert Heinrich (Heinz) Andrejewski (born in Bernburg 09.02.1889, died in Leipzig 23.08.1966) from the 1910s until the 1970s. Several postcards depict Andrejewski and the ensembles in which he worked, others mainly colleagues he met during his career. Holes made by pins in some postcards show that they also served as wall decoration. Some of the postcards described were used to arrange engagements. The collection was donated to the archive in 2019 by the musician’s granddaughter, Petra Andrejewski (Moritzburg).

Collection Anon. 1 (Anonymus/Anonyma 1)

Main focus of the collection: mainly topographic postcards, artist postcards, motif postcards
Time span: mainly the first two decades of the 20th century
Size: 534 postcards
Collection completed
Indexing: fully digitised, fully indexed, fully unlocked
Original order: The box containing the collection was sifted through several times before it was given to the archive. The current order reflects the order in which we received the postcards when they were donated.
IDs: os_ub_0018245 to os_ub_0018778
Collection history: The collection was donated to Prof. Dr. Sabine Giesbrecht by a person who wishes to remain unnamed. According to Mrs. Giesbrecht, the collection was found in a cardboard box in the household waste. Mrs. Giesbrecht took some postcards which could not be identified so far for her own collection. The original extent of the collection is no longer retraceable. The collection contains postcards from many European countries, mainly to Hungarian addressees. As the addressees are very different, it is presumably not an exchange of correspondence, but a specifically intended collection, probably started in Hungary. The latest postcards (from the 1970s) are two views of Osnabrück Castle. Other, older postcards, e.g. from the Osnabrück area, suggest that the collection was continued at a location in or around Osnabrück.
Funding: The digitization and indexing of the collection was made possible by the Deutsche Digitale Bibliothek as part of the NEUSTART KULTUR program funded by the Federal Government Commissioner for Culture and Media (BKM).
Literature on the collection:

Collection history: The postcards were collected by an unknown collector. During the time he collected the cards, he was part of the crew of a Rhine ship and travelled across Germany.

The collector’s granddaughter gave the postcards to Frans Bork, who donated them to the archive in 2019. 
Literature on the collection:

Collection Anna Dietrich

The collection is archived, but not yet fully indexed. The following information is provisional.
Main focus of the collection: First World War, topographical maps, portraits of women and girls and of the german imperial family.
Time span: 1904-1921
Size: approx. 490 postcards
Collection completed
Indexing: not digitised, not indexed, collection can only be accessed in the archive
Original order: The original order cannot be restored, so the cards have been sorted chronologically down to the day as far as possible. The album that was added later, however, has been preserved in its original order.
IDs: The collection has not yet been digitised and indexed.
Collection history: The cards originate from the property of Anna Elisabeth Bartmann (born in Damerau/Prussia 07.06.1895, died in Lingen 02.11.1941), married Dietrich (m. 1913). The collection contains the postcard correspondence of the young woman who went to school in Danzig and married the teacher Leo Franz Dietrich (born in Gr. Jenznick/Prussia 18.10.1887, died in Lingen 25.08.1972) in 1913 at the age of 18. He was called up as a soldier shortly afterwards and remained in service until the end of the First World War. He sent his wife numerous postcards reporting on his experiences at the front. After the Treaty of Versailles came into force (1919), the young family left the former East Prussia. They settled in Lingen in the Emsland region. Via Anna Dietrich’s granddaughter, Michaela Goldstein, and her husband, Uwe Goldstein, this remarkable document of historical importance found its way into our archive in 2022. An original preserved collection album was added in 2023.

On the other hand, the collection was created during his time as a project collaborator at the archive Historische Bildpostkarten Universität Osnabrück (Feb. to Oct. 2020) as a supplement to the collection of Prof. Dr. Sabine Giesbrecht, which is the reason why, for example, a special focus was placed on foreign cards (English song postcards, Italian opera). As a particularity it should be noted that the collection contains four autographs, namely of the composers Carl Isenmann (os_ub_0021016), Wilhelm Kienzl (os_ub_0027640), Hans Sitt (os_ub_ os_ub_0027639) and Paul Zilcher (os_ub_0027638).

Postcard correspondence of the sculptor Carl von Mering

Main focus of the collection: topographic postcards, artist postcards, motif postcards
Time span: mainly the beginning of the 20th century
Size: 285 postcards
Collection completed
Indexing: fully digitised, fully indexed, fully unlocked
Original order: No longer reconstructable. See collection history
IDs: various unrelated IDs within the Giesbrecht Collection, outside os_ub_0018803 to os_ub_0018850 and os_ub_0018996 to os_ub_0019170.
Collection history: These are postcards from the correspondence of the artist and sculptor Carl von Mering and his wife Clara, née Eberhardt.
Many postcards date from the time before their marriage.
Carl von Mering‘s granddaughter, Christa Lippold, gave the postcards from the Merings‘ correspondence to Prof. Giesbrecht. She took numerous postcards and arranged them in different categories of her collection. The remaining postcards were handed over to the archive in 2018, together with other selected items. Only during the re-digitisation did the connections become apparent so that all the cards not included by Prof. Giesbrecht in her collection could now be combined in the “Collection Carl and Clara von Mering” which can be found in the “Smaller Collections”. With the help of a search for the name of the donor, Christa Lippold, or for the names of the legatees Carl von Mering and Clara von Mering, it is easily possible to reunite all the cards in the correspondence, including those from the Giesbrecht collection. The legacy of Carl von Mering is archived at the Rheinischen Archiv für Künstlernachlässe in Bonn. 
Funding: The digitization and indexing of the collection was made possible by the Deutsche Digitale Bibliothek as part of the NEUSTART KULTUR program funded by the Federal Government Commissioner for Culture and Media (BKM).
