Ayers, Chinese Ceramics in the Baur Collection, vol. 2, Geneva, 1999, pp. 246-7, no. 340; and a yellow-enamelled brush pot with a scene of landscape and figures bearing Daoguang mark in the Palace Museum, Beijing, illustrated in The Complete Collection of Treasures of the Palace Museum, Monochrome Porcelain, Hong Kong, 1999, p. 55, no. 49, which has the finely worked details on the rim to imitate bamboo like the present lot.
