WWII A Nazi lesson in racial purity – scarce set of approx 38 celluloid slides c1935 produced as a lecture on the ‘Science of the Races’ – intended for school children, and clearly part of the general Nazi indoctrination campaign to highlight the advantages of the ‘Ayrian Race’ over other world races. Each approx 10x8 cms and each in original envelope with printed lecture script. Not a complete set, but in good condition.
