What interests me most about the artwork of Banksy is the current frenzy surrounding it. I've been slagged off quite a bit in the comments recently for continuing to document the phenomenon. It's not the actual art that appeals to me so much but the way in which it comments on pop culture and the art world and the way that culture continues to feed it.
Like Warhol, Banksy tends to throw a lot of fuel on the “what is art?” debate.
On that note, Banksy has responded in a very Banksian fashion (see illustration above) on his website to the sale of several of his works at Sotheby's.
