Gee’s Bend quilt lovers young and old, near and far, newly converted and veteran, take note: the Souls Grown Deep Foundation has given 15 of those abstract wonders—by key figures like Mary Lee Bendolph, Delia Bennett, and Annie E. Pettway—to the Philadelphia Museum of Art as part of a gift of 24 pieces that also includes works by Thornton Dial, Lonnie Holley, and Bessie Harvey.
