Die KdF Stadt - Eine frohe Erinnerung an die 11. Olympiade in Berlin (1936)

Kraft durch Freude (German for Strength through Joy, abbreviated KdF) was a large state-operated leisure organization in Nazi Germany.
It was a part of the German Labour Front (Deutsche Arbeitsfront, DAF), the national German labour organization at that time.
Set up as a tool to promote the advantages of National Socialism to the people, it soon became the world's largest tourism operator of the 1930s.
