Very rare receipt given to the sender of a packet to a Polish relative who was a KL Stutthof inmate, imprisoned in a sub-camp called Elbing-Neustädtder Feld Lager XVIII. This receipt has the Hitler post-stamps of Böhmen und Mähren, and it's printed in 2 languages: German and Czech. On the reverse, also bilingual, with important instructions. Condition is really good. Sent in 1943.
