This is not a photo opportunity : the street art of Banksy
(Book)

"This Is Not a Photo Opportunity is a street-level, full-color showcase of some of Banksy's most innovative pieces ever. Banksy, Britain's now-legendary "guerilla" street artist, has painted the walls, streets, and bridges of towns and cities throughout the world. Once viewed as vandalism, Banksy's work is now venerated, collected, and preserved. Over the course of a decade, Martin Bull has documented dozens of the most important and impressive works by the legendary political artist, most of which are no longer in existence. This Is Not a Photo Opportunity boasts over 200 color photos of Banksy's public work on the walls, as seen from the streets" --,from publisher's web site.
