Sometimes, art is where you find it. At Philadelphia's Earth Day parade today, locals need look no further than 10 recycling trucks newly wrapped with colorful floral, aquatic, avian and other pro-environmental designs. Students in the city's Mural Arts Program created the wraps, earning valuable experience for their future as starving artists scrounging through refuse bins for food and clothing. Kidding, kidding. They'll all get jobs—maybe they'll work at big ad agencies and create wraps for trains and buses. Of course, wrapping sanitation vehicles in ads is unlikely. Client products and services would be too closely aligned with—what's the word?—ah, yes ... trash. Such ironic illustrations of truth in advertising would be a bit too much to bear.
