A very finely enameled Chinese export porcelain handled cup with a broad band of butterflies and insects within floral and diapered borders.  Produced after designs by Dutch artist Cornelius Pronk, commissioned from the Dutch East India Company.  As these pieces very rarely appear on the market, we assume that this was a one-off special order tea service.  Good condition with only a line to the interior with a professional museum seal, the enamels in brilliant order. 2 3/4″ tall. Circa 1735-1740.
