Banksy is the gold standard when it comes to urban street art. His legendary reputation has only grown since the 2010 release of his intriguing movie, “Exit Through the Gift Shop.”

To promote the film, Banksy went into super-overdrive and attacked city walls across North America like there was no tomorrow. The result is an incredible collection of thought-provoking, clever work that only the brilliant Banksy could come up with. Here are Banksy's top 12 masterpieces of 2010.
