The London auction house claimed the total set a record for contemporary art auctions in Europe.

Bacon's 1969 Study of Nude With Figure In A Mirror was sold to a European private collector for nearly �20m.

Three Self Portraits by Warhol, a rare trinity of canvases from 1986, fetched almost �11.5m from an anonymous buyer.

Another of Bacon's work - a small portrait thought to be the first portrayal of his last great love, John Edwards - sold for about �2m.

Koons' sculpture

Concetto Spaziale, La Fine Di Dio, by Lucio Fontana smashed all expectations when it sold for more than �10m, some �6m more than the estimated sale price.

The sale also broke Fontana's previous record price of �2.4m.

Jeff Koons' sculpture Kiepenkerl was expected to sell for between �1.5m and �2.5m but fetched more than �3m on the night.

Pieces by Gilbert and George, Bridget Riley and Andreas Gursky were also auctioned off.

Buyers at Sotheby's pay a premium of between 12% and 25% to the auction house which is included in all the sale prices.
