Bowie's hand, Emin's legs, Bremner's voice

THE ART world is to be given a rare opportunity to compare and contrast the work of bad girl Tracey Emin with the more conventional style of HRH the Prince of Wales.

A charity auction to be hosted by Rory Bremner in Londonon 29 November will also include a painting by the rock star David Bowie, as well as works by Gavin Turk, Bridget Riley and more than 60 others. A wider variety of unharmonious styles has rarely been seen in public.

A two-day exhibition will precede the auction. Entitled, "Together: artists in support of the homeless", it is being held to raise money for the Passage charity, to help to refurbish an office block in Victoria, central London, to provide a 50-bed night shelter for the homeless. It had its origins in a picture of a hand with a hole in it donated by Bowie earlier this year. Prince Charles followed with a lithograph of some cypress trees entitled Greek Landscape in Summer. Emin's work, My Beautiful Legs, is a 1995 silk screen which, to the relief of the auction managers, "has no bits attached, or fluids". "It is a sketch of a pair of legs, with shoes," says Jessica Shepherd-Smith, the auction organiser.

Gavin Turk has provided a pair of shoes made of newspaper and parcel paper. On the underside of one shoe is written "Just do it", a slogan used for Nike trainers - while the artist's name is written on the other. The piece was completed this year. Other works have been provided by Matthew Radford and Peter Howson, the war artist.

Andrew Hollingsworth, at the charity headquarters, says the night shelter will cost pounds 3.5m in total, but only pounds 680,000 more needs to be raised.

Emma Underhill, an artist and one of the organisers, said: "We have been delighted with the response and never imagined when we began this that we'd have 70 pieces. Many of the biggest names in British art have contributed and it will be a unique event." The exhibition is at the Lincoln Centre, 18 Lincoln's Inn Fields on 28 and 29 November.
