U.S. casino magnate Wynn's ex-wife bought $142 million Bacon triptych - report

REUTERS - The billionaire ex-wife of U.S. casino magnate Steve Wynn was the mystery buyer of the triptych by Francis Bacon that became the world's most expensive painting sold at auction last November, a newspaper reported.

Elaine Wynn - who divorced the Wynn Resorts Ltd Chairman in 2010 - paid $142.4 million for "Three Studies of Lucian Freud" at Christie's in New York after a dramatic 10-minute sale, the Wall Street Journal reported, citing two unnamed sources.

Representatives of Wynn and Christie's did not respond to requests for comment.

The three-paneled work, painted in 1969 and which carried a pre-sale estimate of about $85 million, depicts the Dublin-born painter's friend and fellow artist on a chair.

Never before offered at auction, it eclipsed the $119.9 million that Edvard Munch's "The Scream" raised at Sotheby's in May 2012.

The 71-year-old buyer leant the painting to the Portland Art Museum but it could end up at the Los Angeles County Museum of Art, where she is a board member, the Journal said. Wynn also has homes and ties to cultural institutions in Nevada and Idaho, it said.

Another celebrated Bacon portrait, of his lover and muse George Dyer, could raise up to 30 million pounds at auction in London next month, Christie's said on Wednesday.

Wynn, a co-founder of the Wynn casino empire, has an estimated net worth of $1.9 billion, according to Forbes.

She also owns a work by Lucian Freud, while her former husband's art collection includes works by Rembrandt and Degas, the newspaper said.
