A similar dish with Yongzheng mark in the Palace Museum, Beijing, is illustrated in Kangxi, Yongzheng, Qianlong: Qing Porcelain from the Palace Museum Collection, Hong Kong, 1989, p. 243, no. 72, and another was sold at Christie’s Hong Kong, 26 April 1999, lot 680. Related Yongzheng “three fish” dishes and bowls, based on Xuande-period designs, with a pattern of three red fish on a white ground, appear to have been produced on a greater scale than the copper-red dishes reserve-decorated with four fish. A pair of Yongzheng dishes with three copper-red fish on a white ground was included in the Hong Kong O. C. S. Exhibition of Chinese Blue and White Porcelain and Related Underglaze Red, Hong Kong, 1975, no. 129.
