Approver Comments:
I agree that these are two of the many possible Abramowiczes who may have signed this name. Note that the 1933 date goes with Abram and the 1932 date with Calal; likewise, Abram lived at Alexanderhofstrasse and Calal at Sulzfelderstrasse. Thanks for starting the research on this signature!
Please remember to enter all addresses: Calal also lived at Plac Koscielny 6 and, after January 7, 1943, on Matrosenstrasse; Abram also lived at Buschlinie 87.
