QIANLONG SIX-CHARACTER SEAL MARK IN UNDERGLAZE BLUE AND OF THE PERIOD (1736-1795)

This design and color combination appears to be based on Kangxi examples, such as the dish illustrated in Mayuyama, Seventy Years, vol. I, Tokyo, 1976, p. 349, no. 1047. Another Qianlong mark-and-period dish with similar design was sold at Christie's New York, 13-14 September 2012, lot 1489.
