Charles Mason Blackmon was a collector of Asian art. Following his graduation from Harvard University in 1934, Charles’ interest in Asian culture grew when he was stationed in Southern China during World War II. His approach to collecting was thorough, as he believed that “determination in finding various objects and a knowledge of them” were important to building a well-rounded collection. Beginning in 1961, Charles became involved with several notable institutions, and over the years loaned some of his most important pieces to museum collections.Condition: Good condition with expected old wear, few minuscule chips and nicks to the inner and outer rim, and minor calcifications.Weight: 92.7 gDimensions: Diameter 11.2 cmAuction resultparison:Type: Closely relatedAuction: Christie’s New York, 20 September 2013, lot 1730Price: USD 11,250 or approx.EUR 14,000 converted and adjusted for inflation at the time of writingDescription: A greyish-green jade bi, Warring States period/Han dynasty, circa 3rd century BCExpert remark:pare the closely related form and decoration with similarma spirals within a grid pattern.
