While a number of Qianlong examples of this design have been published and sold at auction, Yongzheng blue and white examples, such as the present dish, appear to be very rare. A similar Yongzheng example of comparable size is in the S.C. Ko Tianminlou Collection, illustrated by Liu Liang-yu, A Survey of Chinese Ceramics, vol. 5, Taipei, 1991, p. 95. Compare, also, a yellow-ground blue and white dish in the Percival David Foundation, illustrated in Oriental Ceramics, The World's Great Collections, vol. 6, Tokyo, 1987, no. 247.
