Two sides to Every Coin-part 1

Here is the official NY Post account of PosterBoy's arrest.

If you're one of the subway system's most-wanted - but anonymous - vandals, it may be a good idea to keep your mouth shut.

A guerrilla "artist" known as "Poster Boy," who cuts up and rearranges subway advertisements into designs of his own, was busted after an undercover officer overheard him bragging to a girl about his exploits at a party, sources said.

Henry Matyjewicz, 27, of Bushwick, Brooklyn, was arrested Friday at an art show at a SoHo loft that featured his work and was hosted by a group called Sly Art vs. Robot City.

Transit police had gotten a tip that Matyjewicz would be at the party, advertised as "The Friends We Love Festival," and sent the undercover officer, the sources said.

Poster Boy's work has caused tens of thousands of dollars in damage to ad campaigns, and he has long been a thorn in New York City Transit's side.

But not knowing what he looked like, the officer was able to nab him only after he overheard the artist/vandal bragging to the girl, the sources said.

He was charged with counts of criminal mischief, graffiti and possessing a tool to make graffiti. He was also held on a warrant for shoplifting in Manhattan last August, court records show.

Matyjewicz was held on $750 bail. No one answered the door at his Brooklyn apartment last night or at the loft where the party was held.

Matyjewicz had recently made efforts to become part of the mainstream art scene.

In a recent interview with the Web site Gothamist, the former art-school student boasted he was so well known for his work that "I have Vandal Squad officers hounding me for autographs."
