Billionaire collector William Koch is sending another group of paintings to Christie's New York November sales, expected to bring more than $40 million, after parting with $84 million of American art at the house in January. The new group turns to European and Latin American art, and its leaders are both estimated at $12 million to $18 million.

The top lots are Claude Monet's Champ d'avoine et coquelicots, an 1890 field of oats and poppies near Giverny that Koch bought in 1985, and Paul Cézanne's Tasse, verre et fruits, a still life of apples, a cup and a glass from around 1877 that he acquired in 1986. Both will appear in the 20th Century Evening Sale. Behind them come a Matisse nude inspired by the ballet La Bayadère, estimated at $5 million to $7 million, and a Degas pastel-over-monotype ballet scene at $3 million to $5 million; the Degas was first bought directly from the artist by Philadelphia collector Annie Riddle Scott on Mary Cassatt's advice, and another impression of the same monotype is held by the Clark Art Institute.

Further works include a 1929 Diego Rivera flower seller and a 1950 Joan Miró painting, each estimated at $2.5 million to $3.5 million, a 1971 Marc Chagall dancer at $1.2 million to $1.8 million, and a 1909 Gabriele Münter child with a doll at $900,000 to $1.2 million. The group will be spread across the evening sale, the Impressionist and Modern Art day sale and the works on paper sale during November marquee week.

The consignment extends a remarkable run of selling: Christie's sold $28.8 million of Koch's wine in June 2025, and in under two years he has parted with more than $112 million in art and wine. Neither Koch nor Christie's has publicly tied the sales to a broader plan, though Koch is reported as hoping other collectors will enjoy the works as he has.
