I have a photo portrait postcard of my great uncle that he sent to my grandfather from Poland in the 1910's. The back of the postcard is stamped with the name of the photo studio "E. Hawin, Zambrow". Would anyone have any information about E. Hawin as to exactly where in Zambrow his studio was and how long it existed? It would also be interesting to have information about E. Hawin himself. My great uncle was probably a resident of Zambrow and I wonder if he would be listed in a Zambrow directory?
