In order to help both the environment and notion of urban revitalization, Quaker City Mercantile did some work (for an almost non-existent fee) for the non-profit PhillyCarShare. The ads are really simple, but that's because the message is too: WALK when you can, RIDE mass transit if possible, and SHARE your ride instead of owning a car. We could have been more clever, but why? It works. These appeared as bold bush shelters throughout the city of Philadelphia.
