Warhol manager's art for sale

A Warhol portrait of Prince Charles is up for auction

The extraordinary art collection of Andy Warhol's business manager is being auctioned at Sotheby's, New York, on Wednesday.

Frederick Hughes, who was Andy Warhol's business manager for 25 years and the executor of the artist's estate after his death, amassed a huge range of antiques and art works.

The 350 lots of furniture, decorations and art works are expected to raise more than $2m (£1.38m) - part of which will go to other art societies and collections.

It is an extremely eclectic collection

Going under the hammer will be photographs by Cecil Beaton, Helmut Newton and Man Ray, paintings by Joan Miro and a drawing by Pablo Picasso, entitled Femme Nue Couchée, which is expected to fetch $25,000 - $35,000 (£17,000 to £24,000).

Mr Hughes and Andy Warhol were introduced in 1967 at a party.

Warhol appointed Mr Hughes to run his studio and the manager went on to become a friend and confidante to the artist.

When Warhol died, Hughes became the artist's executor and oversaw a successful sale of the artist's belongings at Sotheby's in 1988.

Hughes was Warhol's business manager

Hughes later founded the Andy Warhol Foundation for the Visual Arts in New York City.

Works by Mr Hughes' former employer make up part of the collection and include a large painting of Prince Charles with an estimated value of $70,000-$90,000 (£48,000 to £61,000).

There are other royal portraits in the collection from the Tudor era, including a portrait of Charles I as the Prince of Wales, attributed to Paul van Somer and estimated at $40,000-$60,000 (£27,000 to £41,000).

Also up for auction are items of furniture, antique toys, Native American artefacts - and an 18th Century costume that Mr Hughes once wore to Mick Jagger's birthday party.
