A Picasso portrait of his mistress and "golden muse" Marie-Therese Walter fetched $45 million on Tuesday at the beginning of the auction series of impressionist, surrealist and modern art in London.

Sotheby's sold the painting, “Femme assise pres d’une fenetre,” from 1932, depicting Walter sitting in a black armchair, for more than six times its previous sale price in 1997 of $6.8 million.

In 2010, the artist's "Nude, Green Leaves and Bust," another image of Walter as a young woman, set a record for Picasso at $106.5 million in a Christie's sale in New York. The work came from the estate of Los Angeles art patron Frances Brody, who died at age 93 in 2009.

Earlier in this Tuesday's sale, Egon Schiele's 1914 "Lovers (Self Portrait With Wally)" brought $12 million, earning a record for a Shiele work on paper.

The record-setting Schiele was one of several by the artist sold by the Leopold Museum in Vienna as part of a restitution case that involves art stolen by the Nazis in the 1930s. The Schiele series brought a total of $22 million.

Sotheby's sale netted nearly $200 million.
