This is very rare letter sent to camp prisoner when KL was - Zivil Gefangenenlager Stutthof ( civil prison camp ) 1941 !

Letters and any correspondence from and to KL Stutthof it very rare.

Letters sent to camp its much more rare like send from camp.

Prisoners can't keep letter long time , just until next letter come from home.

Also in camp was big problem with paper for example : for cigarettes or toilet paper most prisoners fight to get paper !

Very rare item
