The deep bell-shaped beaker stands on a tall ring foot, finely painted to the exteior with fish among aquatic plants below mountains in the background, the interior with a medallion enclosing further aquatic plants emerging from rockwork, box. 

Note: While the design on the present cup is very pleasing, it appears that this cup would originally have been intended to be further decorated in wucai enamels to complete the design. Two wucai cups with this rare design are in the Palace Museum Collection, Beijing. One is illustrated in Porcelains in Polychrome and Contrasting Colours, The Complete Treasures of the Palace Museum, vol. 38, Hong Kong, 1999, p. 155, no. 32; the other is illustrated in Qingdai Yuyao ciqi, vol. 1, Beijing 2005, pp. 232-233, no. 76.
