The collection contains some 120 letters, dating from July of 1942 to 1950. The majority of the letters are from the Schultze brothers to their mother in Buffalo during their internments between 1943 and 1944. Letters from Robert to his fiancée Helen Anne Rosen are side by side with the three letters from Corporal Alfred Godfrey also to Helen, in which Godfrey tells her (referring to her as Anne) that he loves her. Included as well are letters to Waldemar from the War Department calling for his induction, announcing his sentence, and reporting his progress to Jennie.

All letters written from the brothers during their internment were written and sent on paper and envelopes provided for them. Some of these envelopes have the words "IDLE GOSSIP SINKS SHIPS" on the front, next to the address. Strict rules were posted on the header of the paper from Fort Leavenworth: there was to be no bad news conveyed within, nor news that could possibly upset the prisoner. Also, no letters passed censorship if they were too long to "permit censorship" or if they were not written in English.

Other letters are addressed to Robert, Waldemar, and Jennie Schultze in Buffalo, from the Richmond Avenue Methodist Church, the American Friends Service Committee, various Buffalo Radio Supply customers, and the brothers' attorneys, Jay Barnsdall and Julian Cornell.

Finally, the collection contains a black and white photograph of Helen Anne Rosen, a check for five dollars written out to "cash" from the Buffalo Radio Supply account, a National Service Veterans Insurance card for Waldemar J. Schultze, business cards, and various church donation envelopes sent to the Schultze family from the Richmond Avenue Methodist Church.
