You will be glad to know that, at a recent hearing, Brooklyn’s favorite troublemaker, Poster Boy, was acquitted of all vandalism charges. Hooray! You might also be kicking yourself to learn that Poster Boy, ever watchful of too much media attention (and with good reason), actually made an appearance Friday night to assist with the mock poster-slicing at “Brooklynnovation.” Artists, bloggers and delinquents came together at 3rd Ward, a prominent Bushwick artist facility and popular hangout, to celebrate the work Poster Boy has been doing.

The free Dogfish beer was, unfortunately, all drunk down a half hour into the party, but that didn’t stop anyone from having fun with posters! Actual ads, taken down from public spaces around Brooklyn, were set up on one wall and presliced by Poster Boy himself. Velcro strips were then evenly spaced in three rows along an opposite wall, forming a kind of track for people to attach the poster bits onto. A personal favorite was the Nestlé Quik Bunny’s head, eyes hollowed into perfect black circles, placed over a silhouette of Friday the 13th’s Jason Voorhees. Creepy.

As delighted as folks were to behold the elusive Poster Boy, it seems his cameo was actually pretty necessary. A Pomp & Circumstance editor described her own amateur poster-slicing attempts: “I tried doing it, with just, you know, a box cutter. It was hard!” Not that we didn’t guess already, but Poster Boy, like a Manhattanized Zorro armed with a straight-edge razor, is one smooth operator.

Which doesn’t mean that he was ever really able to relax. On the contrary—throughout the entire event, there was always the possibility of undercover cops lurking in the crowd, just waiting to pounce. And so, with commendable foresight, 3rd Ward kept a back window open in the event that Poster Boy had to make a quick getaway. And he did. Several times. But each case proved a false alarm, and lucky for us, he was able to stay well into the night.—Alex Schechter
