PottWall Jam is an annual event in the calendar of Streetart Initiative Gelsenkirchen. This year for me it was a very special event, as they deviated from their convention to play at a legal wall, such like Schürenkamptunnel (2017) or Nordsternpark (2016) and have chosen a crime scene in Ückendorf, next to the center of the city. Private owners of a number of walls in doorways, at a car park and as highlight, even an open empty building, had given permission to design their walls. And as those walls are private, the pieces will not be overpainted in the nearest future. The locations were scattered between Munscheidstraße, Bochumerstraße and Bergmannstraße. And so I spent my Saturday with running back and forth between 5 spots like a squirrel on drugs, looking for nutlets; and there was plenty to find.
