Georgia O’Keeffe was not the only one in her family with artistic talent. Two of her sisters, Ida Ten Eyck O’Keeffe and Catherine O’Keeffe Klenert, had their own achievements in the art community as well. Their hometown, Sun Prairie, Wisconsin, is honoring them with an exhibit, “The Three Sisters — The Art and Artifacts of Ida, Catherine and Georgia O’Keeffe,” in the Sun Prairie Historical Museum and Library until Nov. 26.
