Fonds comprises photocopies of three works for the piano, which Blume described as "meine gesammelten Werke" ("my collected works"). Two of these – an arrangement of the "Emperor Waltz", and "Variations on an American Folk-Song" – were written in the Sherbrooke Internment Camp in 1942. The third, "Picture book for Veronika" was written later that year in Toronto.
