Book excerpt: Carr, a Canadian, O'Keeffe, an American, and Kahlo, a Mexican, were not close during their lives, but Udall (an independent art historian in Santa Fe, New Mexico), in this carefully reasoned and illuminating study, effectively brings many aspects of the artists' works together to demonstrate a kind of zeitgeist they shared as women developing often surprisingly similar, non-traditional themes in the 1920s. Links between their works are developed in the areas of nationalism, identity, gender, nature, and self through discussion of their paintings, psychology, and artistic influences.
