In November 2010, one of Yeats's works, A Horseman Enters a Town at Night, painted in 1948 and previously owned by Novelist Graham Greene, sold for nearly £350,000 at a Christie's auction in London. A smaller work, Man in a Room Thinking, painted in 1947, sold for £66,000 at the same auction. In 1999 the painting, The Wild Ones, had sold at Sotheby's in London for over £1.2m, the highest price yet paid for a Yeats painting. Adam's Auctioneers hold the Irish record for a Yeats painting which sold for €1,000,000 hammer in September 2011
