I found this drawing in some things my mother had of my father's war service. My mother told me that a German pow had done this drawing after the end of war at which time my father was doing guard duty of post war pows. Mother said my father had told her the soldiers would trade cigarettes to the pow for him doing the portraits of men from photos the GI had in there wallets. I was hoping that maybe someone on here might know any information on the artist.
