This photo really fascinates me, what was it they were trying to show? Two nude girls outdoor? Why was the one posing on her knees, and what is the purpose of hand of the woman standing, is if floating in the air, was it to spank or to please? The models are the sisters Grete and Friedl, this photo was taken in 1932.

This photo was taken by Gerhard Riebecke, and is currently For Sale via auction.
