The collection consists of:

Five typed documents, including a letter written by Fischer in German and its English translation and a letter written by Keissler in German, a copy, and its English translation. Both letters are written to the botanist and anthropologist Harley Harris Bartlett (1886–1960), then head of the University of Michigan's Department of Botany. The letters represent an effort to find Fischer employment in the United States due to "the great political change here", referring to Germany's recent annexation of Austria on March 12, 1938.

Gustav Fischer's business card, which includes a photograph of him and his residential address.
