Graffiti artist-cum-photographer Nils Müller has been a part of the graffiti world for years. His new book of photos, VANDALS, takes you inside the world of tagging and trainwriting around the world, from Paris to Bucharest to New York City. Unlike many graffiti books which focus on finished works of art, Müller is far more interested in capturing the graffiti as it's made. The book is scheduled to come out later this month. In the meantime, check out some preview images (click to see them full-size) and wish you were that bad-ass.
