Graffiti Planet is a nice little picture book, compiled and intro’ed by KET.  Nice representation of graffiti from all over the world, and the differences of styles from various regions is entertaining.  A bi-fold is dedicated to a 9/11 tribute wall that five crews collaborated on in Queens; though perhaps the most impressive piece, at least from an execution perspective, is the tag by BOND in the Himalayas.  His tag stands proudly 4500 meters - or almost 3 miles - high in the sky.  Seriously, how???
