KL Dachau prisoner envelope . Letter sent by Polish prisoner to a woman in Litzmannstadt probably mother . Inside this letter we found letter but we are not sure if this connected because its not regular type of camp letter .  Letter is written in German.  Envelope it was sent by prisoner Biernacki Boleslaw  number 11939. I still has the post stamp and also the censorship  ink stamp. Condition is excellent and it is a great example of KL Dachau correspondence for any collector.

We find in German archives two documents after him , copy below
