Compare the similar gui, also dated early Western Zhou, illustrated by J. Rawson in Western Zhou Ritual Bronzes from the Arthur M. Sackler Collections, vol. IIB, The Arthur M. Sackler Foundation, Washington, D.C., 1990, p. 385, fig. 43.1. Another similar gui with a short inscription, previously illustrated by Shang Chengzuo in Shi er jia jijin tulu, Nanjing, 1935, ju 7a, inscription ju 8a, is also illustrated, p. 385, fig. 43.1, which the author describes as having a more substantial ring foot, which is similar to that of the present gui, and which he goes on to describe as "a feature apparently fashionable in the early stages of Western Zhou."
