The honor of auctioning off the private art collection of French fashion designer Yves Saint Laurent and his partner Pierre Berge, shown above at Saint Laurent's funeral, is a huge get for Christie's. Christie's will work with the auction house Pierre Berge and Associates on a planned February 2009 auction. The items to be sold will be announced in September. The collection is composed of several hundred pieces including Renaissance jewelry, paintings by Picasso and Matisse and manuscripts by authors such as Gustave Flaubert and Andre Gide. Experts say the auction could bring in close to $800 million.
