The New York Metropolitan Museum of Art (MET) is going to receive an amazing gift pretty soon. Leonard A. Lauder, a large philanthropist and cosmetics tycoon, will donate 78 Cubist works to the museum, a deed the MET describes as "truly transformational." The pieces are valued at more than $1 billion. The MET will receive 33 works from Pablo Picasso and 17 by Georges Braques. The artists are thought of as pioneers of the Cubist movement. The museum will also acquire 14 pieces by Fernand Leger and 14 others by Juan Gris. Lauder's art collection was accumulated over almost four decades.
