Call it what you will—street art, culture jamming, or protest. I'll call it some guy who's been going around London and graphically hacking the heads off of models in all types of ads. With fantastic attention to detail. Pictured: Carrie Bradshaw, improved. You know all the cool kid brands are just dying of impatience waiting for him to hack up one of their ads. Lovely. Two more pics of the mystery chopper's graphic, allegorical work, after the jump.
