In July 2014, the good people of Immigration Office Bremen agreed to host an exhibition where everyone was invited to show their work (except for assholes, as it specifically stated on the poster and flyer). The gallery opened doors three hours before the vernissage for people to hang their work.
Each work was photographed and printed on sticker paper for the diy catalogue, an A6 format sticker booklet that could be filled out by all artist attending the opening. See more here.
