Although bowls of this type are known from the Qianlong period onwards, it is rare to find a pair of bowls complete with covers. An example with cover and also dating to the Daoguang period is illustrated in Geng Baochang, Ming Qing Ciqi Jianding, Qingdai Bufen, p. 145, fig. 190.
A pair of Qianlong bowls from the Percival David Foundation of Chinese Art, is described in Illustrated Catalogue of Qing Enamelled Wares, Revised Edition, London, 1991, p. 45, nos. 897 and 898. See also Oriental Ceramics, The World's Great Collections, vol. 6, 1982, no. 274. Other examples are illustrated in Selected Far Eastern Art in the Yale University Art Gallery, no. 54 and by G. Lang in The Powell-Cotton Collection of Chinese Ceramics, Kent, 1988, no. 90.
