Woman wearing a Beret and Checkered Dress by Pablo Picasso, c. 1937.

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.
