The city of Helsinki has been running a zero-tolerance project for graffiti since 1998: ‘Stop Töhryille!’ (Stop the Scribble!), a campaign targeted against any kind of visual or textual intervention in a public space by a private citizen. Zero Information is a public bill board artwork using tags photographed before their erasure, sourced from the digital images archive of the Public Works Department of the City of Helsinki. The first billboard image is a combination of approx. 400 graffitis and tags joint into a single black-and-white image. The second is a documentation of the act of changing a billboard advertisement. For a few moments, the empty stand is shining with a bright white light. Third is my hand, with a tattoo inked between index and thumb.
