Anti-Advertising Agency and artist Packard Jennings just completed what they're calling the Bus Stop Ad Project - basically an anti-ad campaign in Oakland, California:
The Agency created a survey to poll residents in the neighborhoods surrounding 10 Oakland bus stops regarding what advertising tactics they found most bothersome in their neighborhoods. Jennings then developed targeted illustrations for each neighborhood and the team installed the work.
