Nazi eugenics poster entitled "Feeble-mindedness in related families in four neighboring towns." This poster shows how "feeble-mindedness" and alcoholism are passed down from one couple to their four children and their families. The poster was part of a series entitled, "Erblehre und Rassenkunde" (Theory of Inheritance and Racial Hygiene), published by the Verlag für nationale Literatur (Publisher for National Literature), Stuttgart, Germany, ca. 1935.
