PHILADELPHIA – The Philadelphia Museum of Art is celebrating the 100th anniversary of Ellsworth Kelly’s birth with a new exhibition highlighting an extraordinary group of drawings that Jack Shear, the artist’s longtime partner and husband, has generously offered along with a related painting and sculpture as gifts to the museum. They come just as the museum has dedicated Gallery 275 as the newly endowed Jennifer Rice and Michael Forman Gallery, which has long showcased the early work of Ellsworth Kelly (1923-2015) and will be devoted to artist’s work and legacy.
