YONGZHENG SIX-CHARACTER MARKS IN UNDERGLAZE BLUE IN THREE LINES WITHIN DOUBLE CIRCLES AND OF THE PERIOD (1723-1735)

This delightful design appears to be inspired by Kangxi examples. Compare to a Kangxi-marked doucai bowl with similar design in the Palace Museum, Beijing, illustrated in The Complete Collection of Treasures of the Palace Museum, Porcelains in Polychrome and Contrasting Colours, Hong Kong, 1999, no. 196.
