Auctioneer Christie's says that a drawing by Raphael has sold for about 29.2 million pounds (about $47.5 million).
Christie's says the Italian virtuoso's work has won one of the highest prices ever paid for an Old Master at auction.
A portrait by Dutch master Rembrandt also fetched a high price, selling for 20 million pounds.
The auctioneer said the works were sold as part of its Old Masters and 19th century art sale in London Tuesday.
The sale realized 68,380,250 pounds.
