Sotheby's New York announced it will offer the collection of Chicago philanthropist Jerome H. Stone over a series of auctions this spring. Stone assembled the collection over the course of the 1950s and '60s with the help of his wife Evelyn. It consists of blue chip works by artists such as Fernand Leger, Joan Miró, Alberto Giacometti, Juan Gris, and Marc Chagall, that together are expected to bring in more than $40 million.

Stone, who built his family business, Stone Container Corporation, into a national multi-billion dollar corporation, and later founded the International Alzheimer's Association, often bought from leading dealers including Pierre Matisse and Sidney Janis.
