A painting that brings together two of Britain’s greatest artists could become one of the most expensive modern artworks ever sold when it’s auctioned in New York next month. Christie’s says Francis Bacon’s “Three Studies of Lucian Freud” could sell for as much as $100 million, well above the current record for Bacon’s work. A contemporary art specialist at Christie’s says the market has moved on since Bacon’s “Triptych” sold for $86 Million in 2008 and thinks the Freud portrait could beat that record and possibly fetch $100 million. Bacon’s three-panel portrait of his friend Freud was painted in 1969 and has never been sold at auction. At the same auction, Andy Warhol’s Mercedes-Benz silkscreen is expected to fetch up to 16 million dollars. “Mercedes-Benz W 196 R Grand Prix Car (Streamlined Version, 1954)” is being offered by the Daimler art collection. Warhol’s cars series was one of his last works before he died in 1987.
