description: A photo session in Jerzy Bereś’s apartment showing two young women, including Brygida Serafin, starting the sculpture "Entertainment Mill" (1969/1970). Brygida Serafin is half-naked, turning the crank, the other woman is in her panties, standing in front, she has just passed under the rotating element (male torso with phallus). It is a participatory sculpture. It was purchased by the Milan gallerist Arturo Schwarz in 1973. Schwarz planned to create the Museum of the Avant-Garde of Eastern Europe, but he did not realize the plan. After many years, he sold his collection at auction. From that moment on, the fate of the sculpture is unknown. On the right, you can see a lamp made by Bereś, on the wall of his "Drawing I" (1962).
