Very rare letter sent by a Polish inmate from KL Natzweiler-Struthof in Alsace in 1944. Sent by prisoner with number 10443, letters from this concentration camp are rarely seen. Letter is written in German to his relatives and it has one post-stamp still glued and the camp censorship ink stamp that approved the letter. Letter is short tough. Letters from this particular concentration camp are scarce and very uncommon and it's a good opportunity to get one without any doubt. Condition is very good.
