Last week, Deuce Seven put up a striking painting on the Williamsburg Bridge-- but it only ran for a few days before getting buffed. The sign didn't remain clean for long, of course: this busted throwup is currently running there. Even graffiti haters have to admit there is a difference between these two pieces, and that makes us wonder: if the sign isn't going to stay clean anyway, why buff a great piece in the first place?
