Courtesy of the Wooster Collective, I bring you this picture of a fightback against the fact that city dwellers are exposed to 5000 advertisements or urban spam a day.

No permanent damage or spray-can is involved, but the message is communicated in a way that the various marketing departments should appreciate. I'm not sure they will though.
