Masterpieces by Picasso and Van Gogh on display at Christie's

Paintings by Picasso, Van Gogh, Monet and Rubens went on display in London today in an exhibition of highlights from "the richest and most exciting" summer art auction season in a generation.

Juxtaposed: Masterpieces through the Ages, organised by Christie's, will include more than 80 works of "museum quality".

Leading pieces include Portrait of Angel Fernández de Soto by Picasso, with an estimated sale price of £30-£40 million, which is being offered by The Andrew Lloyd Webber Foundation.

Jussi Pylkkänen, president of Christie's, Europe, said: "Many of the works are from private collections and may be bought by private collectors, so this is a rare glimpse of some historically significant works of art."

The exhibition is open to the public until Thursday.
