On May 31, the great American abstract artist Ellsworth Kelly, who is still hard at work in his studio, turns 90. To celebrate, several museums around the country are putting together exhibitions, and, for its part, MOMA hosts “Ellsworth Kelly: Chatham Series.” Chatham is the name of the small town in upstate New York where Kelly retreated to in 1970 after living and working in Paris and Manhattan. It was there, in a rented former theater, that he created a series of 14 paintings. Each work consists of two panels painted in a different monochrome color and joined together to form an L-shape. This exhibition marks the first time that the entire series, a crucial moment in his artistic development, has been presented since its debut in 1972 at the Albright-Knox Art Gallery in Buffalo.

Mondays-Sundays, 10 a.m. Starts: May 25. Continues through Sept. 8, 2013
