A portrait of Kate Moss by graffiti artist Banksy is expected to fetch up to £50,000 at auction.
Portraits of the supermodel by three different artists are being sold on Wednesday.
The works by Tracey Emin, Banksy and Albert Watson are being auctioned at Bonhams in Knightsbridge.
Watson's works include a gelatine silver print of Moss in Marrakech, made in 1993, with a price estimate of £5,000 to £7,000, and a print on aluminium which is expected to make up to £5,000.
A screenprint by Banksy is also going on sale, which was made in 2005 and is estimated at £30,000 to £50,000.
Tracey Emin has made a sketch of Moss which is expected to make £600 to £800. The artist is known for tackling thorny issues such as promiscuity, abortion and nervous breakdowns in her work.
Other items going on sale are a self-portrait of Andy Warhol, and photographs of Elton John and Faye Dunaway.
There are also shots of Sammy Davis Jr and actresses Uma Thurman and Tilda Swinton.
