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 of the sculpture, the other woman is standing behind the sculpture, she is in only panties, pulling up her shirt and reveals her breasts. 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, for the wall of his "Drawing I" (1962).
