Sunflower, New Mexico, 1935 by Georgia O'Keeffe

Georgia O'Keeffe's work has led her to become an icon of feminism. Her paintings, from the large close-ups of flowers to the American landscapes, all display a sense of elegance and vitality and show a deep connection with her surroundings. Marsden Hartley, a painter, admired a certain 'purity' in her work referring to "the quality of a thing or a thought when it has been released from all irrelevant influences."
