One billion dollars (£650m) of Cubist art has been donated to the Metropolitan Museum of Art in New York by Leonard Lauder, the chairman of Estee Lauder.
The cosmetics tycoon and philanthropist has given the museum his collection of 78 paintings, drawings and sculptures by Cubist artists.
The Cubist collection, which experts have called one of the world’s greatest, includes 33 Picassos, as well as works by Braque, Léger and Gris.
Thomas P Campbell, the museum’s director said: “Leonard's gift is truly transformational for the Metropolitan Museum.”
