A bleak self-portrait by the postwar British artist Francis Bacon will lead Sotheby’s upcoming Contemporary Art Evening Sale on February 10, 2015, in London. Two Studies for Self-Portrait (1977) is one of only three diptychs painted by Bacon after the death of his partner, George Dyer. Out of the three, it is the only one ever to be offered at auction. The other double self-portraits remain in private collections.

Another Bacon painting, Portrait of George Dyer Talking (1966), dominated last year’s contemporary art auctions in London. Offered by Christie’s, the painting fetched $70 million -- the highest price ever paid at auction for a single panel by the artist.
