The Frieze Art Fair takes place each October in central London, under a very big tent in Regent's Park. The 2011 edition, the fair's ninth, accommodated 173 galleries, and from the Oct. 12 VIP preview through the Oct. 16 close, 60,000 visitors passed through. It's anyone's guess how much money changed hands -- with those numbers, presumably quite a lot. Despite the sinking global economy, there is money for art in London. There is also art for money.
