By 1999, Bristol, England had become far too small for Banksy. He was already turning into an English street art sensation, and decision to head to London was paralleled by his decision to aim for anonymity. He hid his identity so the police would have a harder time catching him if they had no clue who he was. After all, much of his work was and remains illegal. As Banksy's signature stencils became unmistakable, people were more and more intrigued about the unknown artist. His obscured identity only helped create buzz around his art.
