Unseen since it was acquired by the owners in 1986 and appearing at auction for the first time, this intimate portrait of Pablo Picasso’s golden muse - Marie-Thérèse Walter - was kept by the artist all his life. Dating from 1931, ‘Femme Endormie’ is a rare, fully-figurative charcoal drawing on canvas of a very private moment at the height of their love. From a private family collection of works charting the course of the European avant-garde, this is a highlight of our upcoming cross-category ‘Rembrandt to Richter’ Evening Sale (28 July | London).
