"On the evening of May 15, the Positive View Foundation will present a benefit sale of photographs from the 'Landmark: Fields of Photography' collection, which exhibited at Somerset House in March of this year.

Among the 42 works offered are unique prints by notable photographers from the 19th and 20th Century, including Daniel Beltrá, Nadav Kander and Edward Burtynsky.

Proceeds from the sale will benefit the Positive View Foundation and the Educational Programme it is launching on the evening of the auction.

The Programme aims to support photographic educational projects for underprivileged young people and initiatives that tackle issues of youth crime.

Andrew Page, CEO and Founder of Positive View Foundation, said: '"Landmark: the Fields of Photography" has been a resounding success, with tens of thousands of people enjoying the exhibition at Somerset House.'

He added: 'Our focus is now to ensure that we take the work donated by photographers and use it to change the lives of some of our most disadvantaged under 25-year-olds.'

Christie's said it expects the auction to raise funds in the region of £200,000"
