Very rare postcard sent to Stutthof camp with occasional stamp from Danzig 1944

You can read the prison number as the recipient of this postcarte and the address of KL Stutthof. OLTARZEWSKI MIROSLAW from WARSCHAU born 10/01/1920 prisoner number 35898 .At the top you can see a date stamped by the camp censor. Interesting is the occasional stamp from the 500 Danzig crane. Unfortunately, the card is not in good condition, broken in half, and part of the top off. No less cards sent to the Stutthof camp are very unique.
