Banksy's denial of his alleged unmasking by the Daily Mail is pretty clever.
But if I was Banksy (and, PS, I'm totally not!) I would definitely be claiming the unmasking as a planted piece of performance art making a Barthian commentary on the keen interest in my "true" identity. The plaque next to the gallery exhibition would say: "Planted Unmasking, irony and photograph on news media."
This explanation would work even better if the Mail really nailed him than if it didn't, as I twittered today to my friend @metaeuphoria. Dontcha think?
