This vessel appears to be related to or is a slightly more evolved example of other plain gu-form vessels from the Erlitou Culture, such as those illustrated in Cream of the Pottery from Erlitou, Beijing, 1995, p. 101, fig. 74 and p. l05, fig. 80. Compare, also, the gu with bowstring bands on the lower body dated to Early Shang included in the exhibition, Treasures from the Shanghai Museum, Asian Art Museum, San Francisco, 1983, no. 12. These pottery vessels were imitating bronze prototypes, such as the less elongated example dated to the 16th-14th century B.C. included in the exhibition, Treasures from the Shanghai Museum, Queensland Art Gallery, 1990, no. 5.
