The photography made by Tomasz Sikorski documented Edward Dwurnik’s painting action Wykonanie portretów psychologicznych studentów D.S. „Babilon” (Making of psychological portraits of the students from ‘Babylon’ Dormitory) at the Mospan Gallery. The action took place on May 31, 1976. Between 6 PM and 9 PM, Edward Dwurnik painted 28 images of the students living in the dormitory which the Mospan Gallery was associated with. The portraits were made by acrylic paints on the one huge canvas. The canvas was at the end cut into 28 pieces so every participant of the action could take his or her psychological image with his or her name and surname. Dwurnik’s performance was an exceptional event at the Mospan Gallery, one of a few that were addressed directly to the students from the ‘Babylon’ Dormitory of the Warsaw University of Technology.
