A mammoth private collection of modern art valued at more than $150 million is set to hit the auction block in New York.

The staggering collection — which includes works by Picasso, Matisse, Giacometti and Degas — belonged to the late Frances Lasker Brody and her developer husband, Sidney Brody. She died at age 93 in November and he died in 1983.

The centerpiece of the sale, set for May 4 at Christie’s, is Picasso’s “Nude, Green Leaves and Bust,” which is expected to go for around $80 million.
