Letter sent by an inmate from KL Dachau to his wife in Tirol 1944 only 2 days before the Operation Overlord D Day!

It's the letter version that didn't need an envelope. It was folded to send it with stamp. It comes from Dachau sub-camp ( SS Arbeitslager - Kaufbeuren  ) camp guidelines for the inmates. Letter is written in German and it's completed. Adolf Hitler's post stamp is still glued but missing post office stamp ! Good condition.

We find in German archives few documents about him , copy below .
