"Funding Note: The cataloging of this collection has been supported by a grant from the Conference on Jewish Material Claims Against Germany.\n\nThe photographs were taken by an American liberator named Ray and were given to Bernard F. Engel. The pocket-calendar was obtained by Bernard F. Engal, and the document and booklet belonged to him. Bernard F. Engel donated the collection to the United States Holocaust Memorial Museum in 1992."@en . .
