What was Georgia O'Keeffe's final major retrospective venue during her lifetime?

Georgia O'Keeffe's final major retrospective during her lifetime was held at the Whitney Museum of American Art.

The Whitney presented Georgia O'Keeffe: A Retrospective in 1970. The exhibition surveyed her career across abstraction, flowers, New York subjects, bones, and New Mexico landscapes, bringing together work from different periods rather than concentrating on one motif.

O'Keeffe lived until 1986, but the Whitney retrospective is especially important because it was the first major museum retrospective devoted to her work in New York since the Museum of Modern Art's 1946 retrospective. Later exhibitions and publications continued to reassess her achievement after her death.
