he's a layman's artist...arrested 14 times- usually disseminates his startling, hip images via the street and lackluster (cynical) hope for viral mass appeal. "absurdist propaganda" is his mo. he created the hope image without any affiliation with obama's campaign... obama'ssavvy design people caught it quickly and asked him for a slight redesign.
and an iconic image was born ;)
fairey on this image: "this is an iconic, confident image that isn't just about pandering to the lowest common denominator."
