Very rare receipt given to the sender of a packet to a Polish relative who was a KL Stutthof inmate. Stutthof was the German concentration camp established in Danzig area. It has some Hitler post-stamps and ink stamps from Warsaw, the city from which it was sent. The shipping of the parcel was paid "Dringend" which means Urgent. On the reverse we can read some guidelines related to the parcel shipping. Condition is excellent.
