A Francis Bacon small-format triptych of his lover George Dyer made what Sotheby’s called a ‘landmark’ price of 26.7 million pounds ($45.4 million) in a contemporary art sale that surpassed estimates and set records for some artists. The Bacon, a 1967 work which Sotheby’s said was one of about 40 such triptychs that the artist painted in a format of 11 by 14 inches for each of the three frames, was the star of the show for a packed auction in London that netted a total of 93.15m pounds.
