"David Hockney's Portrait of an Artist (Pool with Two Figures) is coming to auction at Christie's New York and set to become the most expensive work by a living artist ever sold. The monumental 84-x-120-inch canvas is expected to fetch $80 million at the auction house this November as part of the Post War and Contemporary Art Evening Sale" My first thought was: "80 million for a painting of Jon Bon Jovi looking at a pool ?!?! The world has gone mad." But to tell you the truth it really caught my attention. It is fascinating. But 80 million???? Your thoughts on the artist, painting... and value.
