Venerable auction house Christie's has raised art-world eyebrows by purchasing London's Haunch of Venison. The gallery, which represents Bill Viola and Keith Tyson, among others, has branches in Zurich and Berlin and took in nearly $100 million in sales last year. While Christie's says that Haunch of Venison will be barred from bidding at its auctions, many art-world denizens are concerned that the sale represents an alarming conflict of interest. They are saying so quietly, however, so as to avoid the wrath of Christie's François Pinault, one of the most powerful people in the market. As a result of the sale, Christie's representatives said that Haunch of Venison will open a space in New York.
