About August Mosca
Born
1909
Died
2003
Nationality
American
August Mosca (1909–2003) was an American painter represented by an artist record at the National Gallery of Art and by identifiers in several international authority systems. The available public source pack does not establish a particular movement, school, series, or detailed chronology, so those associations should not be inferred from the name alone. Collectors may encounter works attributed to Mosca across a varied auction record that includes paintings, works on paper and prints, as well as less frequently classified sculpture, mixed media, decorative objects, and editions. Because these categories are broad and the present biographical evidence is limited, identifying a work requires close attention to its signature, inscriptions, materials, date, provenance, and physical characteristics. Institutional and authority identifiers help distinguish August Mosca from other people with the same surname, while comparable auction records provide context for objects that can be matched confidently to the artist.

Common works and media
The available auction data places works associated with August Mosca principally in fine art and painting and in works on paper and print categories. It also contains broader classifications for sculpture, mixed media, decorative art, and editions, although the source pack does not provide enough object-level detail to identify characteristic techniques, subjects, series, or edition practices. Each prospective work should therefore be classified from its actual materials, construction, markings, and documented history.
Market and appraisal context
August Mosca auction results should be compared with works that share the same medium, dimensions, date, subject, and attribution status. Condition and restoration can materially affect comparability, as can signatures, inscriptions, edition details, provenance, exhibition history, and catalogue references. Appraisily's public record covers multiple auction categories, but that breadth should not be treated as proof that every object carrying the name belongs to the same established body of work. Realized prices may also be reported with different fee conventions. A responsible appraisal therefore begins with object-level identification and condition review, then considers recent public sales of genuinely similar works rather than relying on a single overall price statistic.
