The three-character inscription may be read, jian zuo yi, 'Jian [had] made [this] vessel'.
This gui is very unusual in several aspects. The sawtooth band cast in low rounded relief appears to be very rare. The dismembered taotie masks, which are similarly cast, are also unusual in the wide spacing between the elements of the masks. Similar dismembered taotie masks can be seen on the tall foot of two gui illustrated by J. Rawson, Western Zhou Ritual Bronzes from the Arthur M. Sackler Collections, vol. IIB, The Arthur M. Sackler Foundation, 1990; one in the Sackler Collections, pp. 416-7, no. 52, the other in the Palace Museum, Beijing, p. 418, fig. 52.5.
