I was allowed to use the poster wall of @artists.unlimited in Bielefeld for the month of July. Actually, I wanted to brush the design on the wall but the weather had announced only rain in the next few days. Then I made a compromise and with energetic support from @aimiliatheofilopoulos, @malteoing, and @finnbruecher I have a 18/1 poster smoothly (!!!) pasted on the wall. That was really fun.
