description: Photo session in Jerzy Bereś’s studio at Siemaszki Street in Kraków, during which Jerzy Bereś activates the sculpture "Altar I (Alarm Clock)" (1972), Maciej Jerzmanowski and Jan Burnat also take part in the session. In the photograph: Jerzy Bereś is standing next to the sculpture and pressing the lever. He is dressed in black, girded with a wide belt. It is a participatory sculpture. It was purchased by the Milanese gallerist Arturo Schwarz in 1973. Schwarz planned to establish 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. Since then, the fate of the sculpture is unknown. On the left side is "Rotunda with a Bell" (1962) by Maria Pinińska-Bereś.
