A Christie's employee poses for a photograph with "Gimcrack on Newmarket Heath, with a Trainer, a Stable-Lad, and a Jockey" by George Stubbs at Christie's in London April 6, 2011. Art used to be known as an "investment of passion"; today for those who can pay, it's a haven with the added benefit of serving as collateral for loans. With credit tight and markets volatile, more of the world's super rich are borrowing against such alternative assets -- including financial professionals. Picture taken April 6, 2011.
