Spotted in NYC: Corporate Anti-Graffiti

Graffiti is illegal, even when corporations do it, though that never seems to stop them. But maybe Spike TV is trying to avoid trouble by creating their new guerrilla marketing ads by removing dirt on the sidewalks on New York City. I think folks living in the city would actually appreciate the ads more if they finished the job of cleaning the sidewalk, but the ads will probably stay there until someone else decides to clean them. [On the same trip that I spotted this I actually saw an old adhesive plastic street ad that the city just painted crosswalk lines on top of!]
