Automobile art - this lifesize, walking, trunk-waving elephant, 8ft tall and 12 ft long, seats 12 and is for sale at the summer Olympia Fine Art and Antiques Fair - now celebrating its 25th anniversary. British- made in the 1940s from toughened paper and wood, the elephant's 10hp Ford engine gives it six mph. The jumbo-sized price, from new exhibitors Hawkins & Hawkins, is pounds 100,000. The Fair, with 400 exhibitors and prices from pounds 50 to pounds 250,000, is from Thursday (11am) until 14 June (0171-370 8186/8212).

It's degree show time. The big draw for talent-spotting is the RCA's Summer Show, attended last year by 35,000 people. Its sculpture show is at the Sculpture School, Howie Street, Battersea, from tomorrow to 14 June and the Fine and Applied Art Show is from Thursday to 14 June (0171- 590 4444). Meanwhile, at the Sheffield Hallam University degree show at the Psalter Lane campus - until Thursday - 21-year-old Susannah Colborn is offering her series of 12 "message cake" photographs (above), inspired by the thought of a mother, faced with a birthday party of obnoxious children, flipping her lid. The photographs are pounds 300 a set in an edition of 12 (0114- 225 2646).

It's tribal art week, too. Bonhams has a 293-lot auction tomorrow (2pm), with estimates from pounds 100 to pounds 18,000, that includes this Dan wooden mask from Liberia.

There's something tribal - Neanderthal, perhaps - about the sculpture of 36 year old Nicolas Moreton. His work would be in public places by now, but for the rude bits. This 18ins tall celebration of fertility, in Hoptonwood limestone, includes a two-inch foetal form that can be removed from a hole at the back. Its title is "Homepride" - "Bun in the oven, you see," says Moreton. Price pounds 4,000. It is among 12 sculptors' work at the annual Young British Sculptors show at the Beaux Arts Gallery, 12/13 York Street, Bath, until Monday (01225-464850).
