Sam Taylor-Johnson, Mario Testino and Frank Auerbach to auction masterworks for charity

Bridget Riley's 'Untitled [towards Fleeting Moment]' (L) and Antony Gormley's 'PATHOLOGY III' (R) will be auctioned off during an online-only sale at Christie's.

Christie's has announced that 48 leading international artists, designers and architects have donated a selection of artworks, which will be offered online from July 15 through 23.

The cross-category auction will raise funds for the British charity Maggie's, which provides free practical and emotional support to people with cancer as well as their family and friends in centers across the UK.

"Art for Maggie's, Everyone's Home of Cancer Care" will auction off pieces that have been donated to the charity by multiple artists and designers.

Among them are Frank Auerbach, David Bailey, Christopher Le Brun, Sonia Boyce, Lucian Freud Estate, Antony Gormley, Lubaina Himid, Michael Craig-Martin, Julian Opie, Sam Taylor-Johnson, Mario Testino, Edmund de Waal as well as Mark Wallinger.

Also participating in "Art for Maggie's, Everyone's Home of Cancer Care" are architects and designers Jamie Fobert, Lord Norman Foster, the late Dame Zaha Hadid, Thomas Heatherwick and Daniel Libeskind.

On offer during the online sale is a 1986 work on paper by English painter Bridget Riley, entitled "Untitled [towards Fleeting Moment]," which is expected to sell for between £25,000 and £35,000 (about $30,730 and $43,021).

Also hitting the auction block are Frank Auerbach's "Study for Chimney in Mornington Crescent" (1987) and Luc Tuymans' recent work on paper "Cloud," which are respectively estimated to fetch up to £18,000 and £50,000.

Additionally, collectors will have the opportunity to purchase an iconic portrait of John Lennon and Paul McCartney taken in 1965 by English fashion photographer David Bailey and a photograph of Dustin Hoffman from Sam Taylor-Johnson's "Crying Men" series.

"Christie's is honoured to be partnering with Maggie's, an organisation whose vital activities support those suffering with cancer at a time when it is most needed. The charity has long believed in the potential of art, architecture and design to create a refuge for patients and their families. It is a powerful statement of support that so many great artists have acted generously in donating to this auction," Katharine Arnold, Co-Head of Post-War and Contemporary Art Europe, said in a statement.

Many of the artists contributing to "Art for Maggie's" have long donated pieces to Maggie's centers across the UK, including Antony Gormley who has sculptures outside both the Dundee and Cardiff centers.

"Art for Maggie's" is one of the multiple charitable sales organized by Christie's amidst the coronavirus pandemic, which has seen a surge in philanthropy according to The New York Times.

This past April, Christie's collaborated with the Warhol Foundation for the online-only sale "Andy Warhol: Better Days," which realized $272,125 to support the organization's efforts to provide emergency relief to artists throughout the United States.
