A portrait by Italian artist Amedeo Modigliani of his lover Jeanne Hebuterne went under the hammer in London on Wednesday for £26.9 million ($42.3 million, 31.2 million euros), Christie's auction house said. The final price for the 1919 portrait, "Jeanne Hebuterne (Au chapeau)" (Jeanne Hebuterne wearing a hat) was well over the pre-sale estimate of between £16 million and £22 million. A Christie's spokeswoman declined to say who had bought the painting, which shows Modigliani's French muse wearing a black hat and with the swan-like neck typical of his style.
