The Metropolitan Museum of Art, the largest art museum in the United States, and one of the largest of its kind in the world, announced this week that it had received a collection of Cubist works valued at roughly $1.1 billion from noted art collector, philanthropist, and cosmetics heir Leonard Lauder.

Thomas Campbell, director and CEO of the Manhattan-based museum, called Lauder’s donation of 78 drawings, paintings, and sculptures a “transformative” gift to the museum that would change the course of its 143-year history.
