Margaret D. H. Keane (born Margaret Doris Hawkins, September 15, 1927 – June 26, 2022) was an American artist known for her paintings of subjects with big eyes. She mainly painted women, children, or animals in oil or mixed media. The work achieved commercial success through inexpensive reproductions on prints, plates, and cups. It has been critically acclaimed but also criticized as formulaic and clichéd. The artwork was originally attributed to Keane’s then-husband, Walter Keane. Soon after their divorce in the 1960s, Margaret claimed credit, which was established after a courtroom “paint-off” in Hawaii, in which Walter refused to participate.
