'Femme au Béret et à la Robe Quadrillée
(Marie-Thérèse Walter) ( Woman wearing a beret and checkered dress ) is an oil-on-canvas painting by Pablo Picasso , which he created in 1937. It is a portrait of Marie-Thérèse Walter , Picasso's lover and muse during this period and was created with elements of Cubism . The painting signifies a transition in their relationship by combining Walter's profile with that of Picasso's new lover, the Surrealist photographer Dora Maar , with whom he began a relationship in 1936. This portrait was produced in the same year as Guernica and The Weeping Woman , a significant phase in Picasso's artistic career. On 28 February 2018, it was sold at Sotheby's auction for £49.8 million, making it one of the most expensive paintings ever sold at an auction in Europe.
