A teadust-glazed vase of this form and size is illustrated by J. Ayers, The Baur Collection, vol. III, 1972, A395; a larger example by George J. Lee, Selected Far Eastern Art in Yale University Art Gallery, no. 378; and a smaller vase in Sekai Toji Zenshu, Tokyo, 1964, fig. 51. Compare also two other beaker vases of this form but without the vertical flanges: the first of teadust glaze, illustrated in Qingdai Danseyou Ciqi, Special Exhibition of Monochrome Glazed Ceramics, 1981, p. 69, no. 30; and the other with a Ru-type glaze, illustrated by J. Ayers, op. cit., 1972, A340.
