Poster Boy is an anonymous collective of American street artists. Their work is primarily in New York City. They use public advertisements and a razor to create collage-like art. The work of Poster Boy is shared on Flickr. The first Poster Boy started his work because he wanted something to do while waiting on the subway. The collective of those that use the name Poster Boy are active online and in the streets even after the arrest of Henry Matyjewicz, a member of the collective. The artist's work is hybridization, using and mixing multiple different pieces to create a whole new art piece.
