Adam and Eve in Wood
No, these are no dolls for sex educational purposes. This was your typical average home decoration set in the 1970s, Adam (with a penis and balls) and Eve (with a vagina) both made out of wood. You could get them in various sizes, but they were all made to fuck! The ones below are the Dutch/German/Belgian version
Rightside: made by/via Tony Futura, On the left: original dolls from the 1970s, found on Mimi Berlin’s atic.
Comparing the wooden objects above also says a lot about design; Then and Now.
