“The Work Is Never Finished: Prints, Drawings, and Paintings” unearths the prolific work of Samella Lewis (1923-2022), an artist, educator, activist, historian and curator. Lewis kept her own practice throughout her life, even as she worked for museums and universities, founded the Museum of African American Art in Los Angeles and launched the periodical, Black Art: An International Quarterly (later published as the International Review of African American Art). As a Black woman who grew up in the segregated South, she transmuted the prejudice her community faced into striking scenes of human connection, many of them sketched from memory and some rendered as linocuts. The exhibition runs through March 7.
