Morton Sosland (1925-2019) had a long and successful career in foodstuffs so it is fitting the sale includes one of America’s culinary favourites.

Thiebaud’s still-life of an Avocado Salad from 1962 was acquired by the Soslands from the Allan Stone Galleries, New York, in c.1968. Typical of the artist’s colourful output that focused on the commonplace objects found in America’s diners and cafeterias, it is estimated at $1.2m-1.8m.

Estelle Sosland was the Nelson-Atkins Museum’s first female trustee. The couple donated one of the nation’s finest private collections of American Indian art to the gallery and in 1994 commissioned the museum’s Shuttlecocks, the sculpture by Claes Oldenburg and Coosje van Bruggen that graces its lawn.
