Memorabilia and possessions from the home of Fred Hughes, Andy Warhol's manager and perhaps the artist's greatest influence, are to be sold at auction on 10 October by Sotheby's in New York.
The collection, taken from the property in Manhattan that Mr Hughes called Hotel Anglomania, includes Warhol portraits of the Prince of Wales and Jackie Onassis.
Mr Hughes, who died in January aged 57, was a long-time friend of Warhol and the executor of his estate. He ran his affairs for decades, presiding over The Factory, the Manhattan studio that formed the centre of Warhol's social and creative world, and publishing Interview, his celebrity magazine.
The collection testifies to the care Mr Hughes took in developing his image as an elegant dandy with faultless style. It is expected to fetch about £1.4m and includes classic furniture as well as artwork, costume jewellery and photos taken at The Factory. A Sotheby's spokesperson, Elaine Whitmore, said: "He didn't really go after the fame, nor could he, because Andy was the artist. He was a man who was a big part of life behind the scenes, and he really pushed Andy into the limelight, and took him to another place when it came to his artwork.
"The sale has everything from toys to very good American furniture, which were the bones of the house, surrounded by anything from whimsical things to old master paintings."
