Pelvis 

Georgia O'Keeffe's "Pelvis" is a striking example of her abstract style, which often focused on magnified, simplified forms. This painting showcases a single, dominant, and isolated blue shape, possibly suggestive of a pelvic bone. The simple composition and bold, contrasting colors emphasize the abstract nature of the subject, inviting the viewer to contemplate the shape's potential interpretations and symbolic meanings. O'Keeffe's use of bold colors and simplification of form is characteristic of her later period, pushing boundaries in the realm of abstract art.
