Go board of mulberry with marquetry

Maker unknown · Diffuse-porous wood; mulberry top, red sandalwood veneer elsewhere; ivory grid, mother-of-pearl points, marquetry · Undated in the Imperial Household Agency record · Shōsō-in Treasures, Middle Section 174

Look at the playing surface first: ivory lines form a nineteen-line grid, as on a modern go board. Then lower your gaze to the openwork legs.
