About William Thon
William Thon (1906–2000) was an American painter and printmaker born in New York City. Active across much of the twentieth century, Thon worked primarily in paint and print media over a career that spanned decades. He spent his later years in Port Clyde, Maine, where he died in 2000. Thon is recorded in major international authority files including the Getty Union List of Artist Names, VIAF, and the Library of Congress Name Authority File, reflecting his established presence in American art scholarship. With over four hundred works documented in auction databases, his output was prolific and continues to circulate in the secondary market. Collectors most frequently encounter Thon's work through auction listings and estate collections.

Common works and media
Thon is known primarily as a painter and printmaker. Works that may appear in appraisal or auction contexts include oil paintings on canvas or panel, watercolors, and works on paper in various printmaking techniques. Collectors should expect a range of sizes and subjects. Without a published catalogue raisonné, attribution and dating may rely on stylistic analysis and provenance documentation.
Market and appraisal context
William Thon's work appears regularly at auction, with over four hundred documented lots, suggesting sustained collector interest and a substantial body of work in circulation. Appraisal value depends on the specific medium—oil paintings, watercolors, and prints each carry different market expectations—as well as the work's size, condition, provenance, subject matter, and date of execution. Comparable auction results from major and regional houses are the most reliable guide to current value. No published price trend data or catalogue raisonné was identified in the available sources, so individual appraisals should weigh recent comparable sales heavily.
