NYC: "Poster boy" makes art with a razor and subway ads
Since January, the 25-year-old has manipulated about 200 underground posters, turning MTA stations into his own public galleries. His pieces are conceived on the spot, and while most subway-poster vandals limit themselves to all-caps obscenities, Poster Boy’s improvised mash-ups recall both the cut-and-paste aesthetic of old punk-show fliers and the fake ads that appeared in circa-seventies Mad magazine: In his hands, AT&T skyscrapers are turned into flaming World Trade Center towers and Heath Ledger becomes a ghostly anti-drug pitchman. Most of his work disappears quickly—MTA employees have even ripped down his work before he’s finished—but you can see it on his sporadically updated Flickr account.
