The Whitney Museum's 1970 major one-person retrospective was titled Georgia O'Keeffe.
The exhibition was a landmark in O'Keeffe's career and was widely recognized as the Whitney Museum of American Art's first retrospective devoted to a woman artist. By then, she had worked across abstraction, flowers, cityscapes, bones, and New Mexican landscapes for decades.
The exhibition title is often confused with later catalog or retrospective titles that add descriptive subtitles. In this question, the canonical title is simply Georgia O'Keeffe, matching the museum exhibition's identification in biographical accounts.
