British artist Banksy goes for a few reasons. For one, he's one of the most prolific and provocative graffiti artists ever to do it. Perhaps even doper than his work is the fact that he's managed to stay anonymous throughout his career. Now, Banksy has pulled off his most impressive work yet. After years of being criticized by government officials as mere vandalism, Banksy has taken over the entire Bristol Museum, bringing to life 100 original pieces, all without unveiling his identity. As usual, the pieces feature political themes, provoking controversy with a touch of humor. If you should find yourself in Bristol anytime from June 13 to August 31, check out the exhibition for free 99.
