Nice poster with advertisement of a conference about prehistory in the Warthegau included in the "Kraft durch Freude" leisure organisation series of cultural activities in Litzmannstadt. This conference was to be held by Dr. Walter Grünberg, the director of the Museum of prehistory of Litzmannstadt, entitled "Die vorgeschichtlichen Grundlagen des warthegaues" (The prehistorical basis of the Warthegau), clearly trying to support the idea that this part of Poland was totally Germanic. This would justify the idea that the Nazi invasion of this part of Poland was a German historical right. This conference was to be given 9. October 1942.

Poster is in very good condition, complete and just folded from origin.
