We have a deep appreciation for uncommissioned urban art, which is an impressive way of saying “graffiti”. This appreciation may have started with using Mr. Sketch scented markers to doodle on the insides of our 3rd grade textbooks, or maybe it was the standard dicks-on-bathroom-walls motif in our high school years. Regardless, we love it. And now graffiti–though often used as a dirty word–is blossoming into a powerful art form and allowing artists to comment on the world we live in (or don’t live in) in creative new ways. From Banksy to Shepard Fairey, Trespass chronicles the works of some of the greatest artists–works that often are removed or painted over shortly after they’re created. A must-have book for those who appreciate.
