“Shape and color are my two strong things,” said the artist Ellsworth Kelly (1923–2015). And that’s exactly how we think of Kelly, whose love of strong shape and bold color is embodied in his “Blue Green Black Red” series, paintings and sculptures made during the last 25 years of his life. It is less known that over the course of his seven-decade career, Kelly would often create collages on postcards, little works that read like footnotes to the large ones. Matthew Marks mixes the large and the small in this exhibition, a combination that offers viewers a unique window into an artist who helped transform the face of abstract art. —Thalia Bonas
