Super rare book on Nazi racial hygiene from 1936 "Menschliche Erblehre und Rassenhygiene". This book was a deep study regarding the supremacy of the aryan race compared to other races that Nazis took for inferior and in some cases subhuman ("Untermensch"). In the pages of this infamous and scientifically less serious book, we can find photos of examples of specimens of different races, underlining the physical differences between all of them and insisting on the supremacy of aryans. Thick book and in very good condition.
