Turner Prize winner Mark Leckey, designer Peter Saville and comic Harry Hill are among those who have donated artworks to help save a gallery after it lost regular Arts Council funding.
More than 60 artists have submitted works to an auction raising money for the Castlefield Gallery in Manchester.
The gallery was one of 200 arts bodies who lost their regular Arts Council England grants in cuts last year.
David Shrigley and Liam Spencer have also donated to the auction, on 30 May.
The gallery has approached artists who have exhibited there over its 28-year history as well as other supporters.
Saville, famous for designing LP sleeves for the Factory Records label, has donated a signed lithograph of his cover for Joy Division's Unknown Pleasures; while Leckey, who won the Turner Prize in 2008, has given a vinyl record used in his recent sound installation BigBoxIndustrialAction.
Harry Hill has offered a mock copy of Truman Capote's novel In Cold Blood, made of oak with "bullet holes" drilled in it, which was created for a recent exhibition in Manchester.
The artworks went on show at the gallery on Friday in advance of the auction.
Other figures who have offered works include Pavel Buchler, who is acting as auctioneer; Haroon Mirza, who won the Silver Lion at the Venice Biennale in 2011; and Hans-Ulrich Obrist, co-director of London's Serpentine Gallery, who was ranked joint second on ArtReview magazine's list of the most powerful people in art last year.
Artist Gordon Cheung, who has donated 80 prints from a portfolio commissioned by Castlefield in 2004, said: "It felt like it was an art space that was supporting emerging artists and the community in Manchester.
"You could feel that it was a really important component to the Manchester arts scene."
Castlefield director Kwong Lee said: "We're trying to raise £20,000, partly to fill the funding gap.
"And we're trying to send a message that we've been here supporting contemporary art development in Manchester and beyond, and we're still here and we aim to continue."
The gallery has lost its ongoing £92,000-a-year Arts Council grant, but has received £98,000 for the next two years under the Arts Council's Grants For the Arts scheme, which allocates money for set time periods.
