Rare Certificate Issued to a Female Jew as Worker
Rare certificate issued in 1942 to the Jewish woman Pinkus Rosenblum from Piotrkow in Poland, that says this woman was employed as worker in a the glass manufacturing company Emil Haebler, that was a supplier of the Wehrmacht amongst others. Certificate comes with her photo attached as well as her daughter's. It's a folded paper and also with some damage due to use and staples oxidation that corroded the paper in some parts. Anyway, it's almost complete and perfectly readable. An example of how Jews were employed as slave labor by Germans in occupied lands! Interesting company ink stamps also visible.
