This November, William I. Koch’s collection returns to Christie’s with an exceptional selection of Impressionist, Post-Impressionist, Modern European and Latin American art. Leading its highlights are Claude Monet’s Champ d’avoine et coquelicots, a picturesque landscape from 1890, among works by Paul Cezanne, Henri Matisse and Diego Rivera, reflecting Mr. Koch’s discerning eye and wide-ranging connoisseurship.

Works from the William I. Koch Collection headline this season’s 20th and 21st Century Art auctions. The selection follows two landmark auctions of Mr. Koch’s collections, continuing a collecting story that crosses centuries and continents.
