Which is why I decided to escape the voucher shackles and head to 15 Oxford Street to Banksy's annual anti-holiday art show/fair, "Santa’s Ghetto," where the star attraction was Sir Banks’ freshly-created send-up of Michael Jackson in a Hansel & Gretel-style tableau. Not a Hoxton hipster elite and only recently aware that Nathan Barley ever existed, I couldn't help but want to dismiss the whole charade as pretentious arty farty fanfare. But despite every gritty toothed intention, I came away without too much enamel grinding.
And surprisingly not because of Banksy's billing. Disappointingly, his Jacko-fied rendition of Tom Ormond's fantasy piece is less than a thriller. But, rather, the most memorable (and viewable from the shop window) was this mocked-up photo by Peter Kennard of Tony Blair taking pictures on his mobile phone against a backdrop of burning oil fields. Not only because it might as well be a real photograph, but because it showed art's power to satirise those things we are left powerless to change. And these days, what is more valuable than a laugh?
