A street gallery was the solution to the task of promoting an art gallery run by the homeless charity fiftyfifty. The proceeds of the event were supposed to go to people in need. The idea was implemented by putting up 200 city light posters in the urban area of Düsseldorf. The gallery presented works of renowned international artists, such as Thomas Ruff or Otto Piene. Merely small price tags, featuring the fiftyfifty logo instead of a price, informed about the event. 60,000 euros of donations were generated this way.
