Got mentioned on ART thread, wanted to give him his own thread.
Can I propose a theory? I think he's Damon Albarn. I mean he'll have a team of people putting the designs up for him but I think he creates them. Some of the text in the Banksy book sounds EXACTLY like some of his lyrics. And he does have an obsession with being seen as a wide-boy while obviously very posh.
AND, what's more: http://uk.geocities.com/sball404/damon-banksy.html
Tell me that doesn't look staged...
