1UP (One United Power) is a name which provokes different emotions within the Graffiti scene: respect, admiration, envy, competitiveness and inspiration. It was almost 10 years ago that 1UP first appeared on the scene, producing work throughout Berlin - from small tags in the subways to large-scaled pieces on walls, skyscrapers or trains. Since they first arrived, no surface in Berlin has been guaranteed to be safe from their creative prowess.
