LOS ANGELES (BBC) - An Andy Warhol painting of singer Elvis Presley could fetch up to $50m (£31.7m) when sold in a New York auction in May. Sotheby’s said Double Elvis “epitomises the artist’s obsessions with fame, stardom, and the public image”. The life-size painting is one of 22 pieces Warhol dedicated to the singer, and will be shown in London, Los Angeles and Hong Kong before the sale. Eight Elvises was sold for $100m (£63.5m) in a private sale in 2008.
