An ink sketch of a female nude, on thin tissue-type paper, unframed, 5 3/4" by 8 1/2", signed at lower left, and dated there 1937 (or 1931), by noted San Francisco artist FRANK VAN SLOUN (1879-1938). This was quickly executed by a trained hand. Van Sloun was born in St. Paul, Minnesota. After art training in New York at the Art Students League under Robert Henri, he was in San Francisco by 1911, where he quickly became a prominent member of the city's art community, as painter, muralist, etcher and educator. Van Sloun painted murals at the Mark Hopkins Hotel with Maynard Dixon. Van Sloun's name is mentioned prominently whenever art in San Francisco in the first half of the century is discussed. Condition: the thin paper has creases, light brown stains in upper corners etc., but most of this could be matted out in framing. Provenance: John Worley, long time San Francisco art dealer.
