There are over 2800 wall murals in the Philadelphia area. The wall art all started by a Reverend in the community. He suggested that those who were caught vandalizing the buildings would have a choice between jail and community service- which would be painting murals. Since then, the community has caught a vision for the murals, now they are throughout the city. There are seasonal tours, each tour covers about 40 walls.
