The art scene is so congested with competitions that going to a gallery is beginning to feel like chancing your luck at a fairground sideshow - there is rarely anything of great value, but you may as well have a go.

This winter Liverpool is hosting the Turner, Manchester has New Contemporaries, and Leeds, lacking an art prize of its own, has established a new one: the Northern Art Prize, open to any artist based between South Yorkshire and Northumberland, with £16,500 up for grabs. (The winner will be announced in January.)

As ever with art prizes, making a judgement is like trying to draw comparisons between carpet slippers and artichokes - literally so in the case of Karen Guthrie and Nina Pope, as vegetables and knitted footwear are among the items included in the bring-and-buy stall they have set up in the gallery. The stall is Pope's and Guthrie's comment on fair trade and requires you to be extremely fair: all donations are to be placed in an honesty box underneath the table. The rice, from a remote Japanese village, is reputed to be the best in the world, and is a snip at £6 a bag.

There is also a south-east Asian influence to Eric Bainbridge's melamine and particle-board sculptures, which were inspired by a trip to Bangkok, but look more like MFI versions of Anthony Caro's welded steel assemblages.

Perhaps it is a sign of the new prize's conservatism that two of the four finalists are landscape photographers: Tim Brennan's enlargements are hazy, digital watercolours captured on a mobile phone, while Dan Holdsworth's iridescent, long-exposure images make the earth look like an alien planet. But 10p in the honesty box says Pope and Guthrie should win.
