Gigaku Mask, Rikishi (Guardian)
This work represents one of the few extant examples of Gigaku mask in early Kamakura period, thought to have made by the influential Buddhist sculptors in Nara. The lips were pursed in a frown and the teeth were not shown, which was derived from the style of Guardian Kings.
