Nick Walker is a British graffiti artist best known for his stencil works that frequently joins the political with tongue-in-cheek humour. Born in Bristol, he was part of the groundbreaking Bristol graffiti scene in the early 1980s and played a significant role in shaping the look of British street art. The artist's most recognisable work features Walker's "Vandal" character, a sharply dressed, quintessential English man in a bowler hat committing mischief on the streets.
