This unusual archaistic zun shape is seen in various glaze palettes during the Wanli period, and is one of the shapes recorded by Geng Baochang in Ming Qing Ciqi Jianding, Hong Kong, 1993, p. 146, fig. 263. For a zun-form vase very similar to the present example, but without the addition of wucai decoration, see the vase illustrated by I.L. Legeza in the catalogue of the Malcolm MacDonald Collection of Chinese Ceramics, London, 1972, p. 57, pl. CVI, no. 286.
