A pseudonymous English graffiti artist, political activist, film director, and painter who scores the walls of city streets with witty imagery and social commentary. His satirical street art and subversive epigrams combine dark humor with graffiti executed in a distinctive stenciling technique. His works of political and social commentary have been featured on streets, walls, and bridges of cities throughout the world. Various cities have removed his "vandalism" and later kicked themselves when they realized it was the works of a master.
