It is rare to find Yongzheng yuzhi marks on bowls of this design. A similarly-decorated bowl of the same size is illustrated in Chinese Art and Design, The T.T. Tsui Gallery of Chinese Art, 1991, pl. 92; another bowl of the same size but with a densely patterned floral design in the Victoria and Albert Museum is illustrated by R. Kerr, Chinese Ceramics, Porcelain of the Qing Dynasty, 1986, pl. 93; two other examples in the National Palace Museum, Taipei, decorated with the four seasonal flowers, are illustrated in Fine Enamelled Porcelain of the Ch'ing Dynasty, Yung Cheng Period, Book II, 1967, pls. 34 and 35. A bowl of a smaller size, also from the T.Y. Chao collection, sold at Christie's Hong Kong, The Imperial Sale, 27 April 1997, lot 55.
Cf. also a Yongzheng yuzhi bowl in the British Museum, illustrated by H. Moss, By Imperial Command, Hong Kong, 1976, pl. 5. The style of this decoration is similar to Qing period cloisonné enamelling on copper, and it has been suggested that the porcelain for such pieces were sent from Jingdezhen to be enamelled at the Palace Workshops in Beijing, opi cit., p. 33.
