Miniature vase in the shape of an ancient ritual vessel (gu)

Pale yellow vase with wide mouth and narrow base. The vase has a flared mouth with a flat rim. The body of the vase is divided into two sections. The upper section tapers down and has raised rectangular designs around the circumference. The lower section is wider and has a design carved into it. The design appears to be some sort of face or mask. There are also raised rectangular designs on this section, which resemble bricks. The base of the vase flares out slightly. The background is dark gray at the top and light grey at the bottom.
