Giving permanence to graffiti. The graffiti and street art performer Markus Wiese is documenting graffiti in Dortmund’s public spaces with photographic material from the past 2–3 years which he is publishing as part of a brochure. By doing so, he links back to the "Ultra Magazin", a magazine he previously issued. A selection of the images have also been exhibited in large formats. Visitors of the exhibition were able to enjoy a free brochure.
