No other Qing dynasty bowl or washer of this form appears to be published, although a small round 18th-century celadon jade covered jar with a comparable design of upright standing geese around the exterior is illustrated in Zhongguo Yuqi Quanji, vol. 6, p. 74, pls. 113-115.
The design of this washer, however, can be found in the Tang dynasty, as seen in a small jar with three turtledoves in a similar configuration, illustrated in Jadeware (II), The Complete Collection of Treasures of the Palace Museum, Hong Kong, 1995, pl. 33.
The composition of bird and beast on the present vessel is also closely related to that on champion vases of the Ming and Qing periods. From the Ming dynasty onwards, a series of double-vases based on Han dynasty prototypes were made popular, the design invariably incorporating an eagle, ying, standing atop a bear, xiong, the combination forming a pun on the word for 'champion'. The birds on the washer could possibly be eagles, but it is more likely that the motif was chosen for its archaistic aspect.
