This portrait depicts Sarah Greenberg, daughter of famous art critic Clement Greenberg (1909-94). The awkward perspective and unfinished look of the image are trademarks of Alice Neel’s style. In this and her other works, Neel paid more attention to the details of the subject of the portrait, rather than their surroundings.
