EARLY WESTERN ZHOU DYNASTY, 11TH-10TH CENTURY BC

The graph cast on the interior of the vessel, qi (possibly a clan sign) can be found on other late Shang and early Western Zhou bronze vessels, such as a bronze jue and a bronze gu excavated from Xiaqiyuan village, Ci county, Hebei province in 1966, illustrated in Wenwu 1974, vol. 11, pp. 93-94, figs. 12 and 25; and a bronze zun in the Avery Brundage Collection, Asian Art Museum of San Francisco, no. B60B1022.

A very similar you, and possibly the current you, is illustrated by Minao Hayashi in In Shu Jidai Seidoki no Kenkyu (Conspectus of Yin and Zhou bronzes), Tokyo, 1986, vol. I, p. 262, no. 61.
