Compare with a near identical Kangxi copper-red and underglaze-blue decorated fishbowl from the Qing Court collection illustrated in The Complete Collection of Treasures of the Palace Museum, Blue and White Porcelain with Underglaze Red (III), Hong Kong Commercial Press, 2000, pl. 190. A very similar fish bowl was sold in Christie's Hong Kong, 26 April 2004, lot 1015.
Compare the bowl painted in copper-red but without the underglaze blue depicting similar dragons among waves, illustrated Sekai Toji Zenshu, 1961, vol. 12, pl. 25. Compare also another fish bowl in the Palace Museum, Beijing, of similar composition, with a prominent underglaze-red dragon above crested enamelled waves and underglaze-blue rocks, illustrated in Kangxi Yongzheng Qianlong, Hong Kong, 1989, p. 43, no. 26, and again in Zhongguo Wenwu Jinghua Da Cidian, p. 420, fig. 860.
Copper-red and underglaze blue decorated fish bowls from this period are more often decorated with carp swimming among water weeds, such as the example illustrated in the exhibition catalogue, The Wonders of the Potter's Palette, The Hong Kong Museum of Art, 1984, no. 11; one in the Palace Museum, Beijing, op. cit., p. 38, fig. 21; one illustrated in The Tsui Museum of Art, Chinese Ceramics, IV, Hong Kong, 1995, no. 54, which sold in Christie's New York, 20 March 1997, lot 93; and another is illustrated Kangxi Porcelain Wares, from the Shanghai Museum Collection, Shanghai, 1998, no. 77.
