A delightful pair of American Art Nouveau cups with porcelain liners, each measuring circa 6.7cm in height and together weighing a gross 193g, net silver weight: 125g. The silver holders stamped to the underside with maker´s marks of Mauser, used from 1887 to circa 1908. The porcelain inner cups hand painted in polychrome enamels to depict floral garlands, monochrome green to the exterior and a fine gold line delineating the rim. Marked to the underside with Lenox porcelain mark in green within wreath, a mark used from 1906 to 1930. Barring any anomalies, the combination of marks would date these pieces to 1906-1908. Stylistic traits appear to confirm this dating. Provenance: From the Brussels estate of the former governess of the family of William Randolph Hearst Jr., a prominent family in the USA. Condition: One short hairline to one porcelain cup, no other significant damages or repairs. Minimal wear commensurate with age. This lot will be carefully packaged and sent by registered and insured mail.
