This seemed like a joke at first scan, but... this book is real. Poster Boy is officially published, as Subway Art Blog points out. The book, a collection of the mash-up artist's finest subway ad scrambles, is called Poster Boy: The War of Art—and it hits bookstores on March 10th. The description reads: "His cut and slash mash-ups of subway platform billboards only exist in New York City, but Poster Boy’s artful and funny appropriations of advertising have gotten him attention the world over." Maybe he'll make enough to post bail next time he's arrested!
