Wanli-marked vessels of this type, lobed in as many as ten segments, are quite rare. A blue and white box and cover of similar form, painted alternately with ascending and descending dragons, from the Percival David Foundation, was included in the exhibition, Ceramic Evolution in the Middle Ming Period, London, 1995, illustrated in the Catalogue, no. 59; and another of similar form, decorated in wucai with a comparable scene of scholars and attendants in landscape, from the Idemitsu Museum of Art, is illustrated in Sekai Toji Zenshu, vol. 14, pl. 263.
