Catalogue entry no. 336 by Max Loehr:
336 Small Crenelated Plaque
Translucent, brownish yellow jade with cream-colored spots. The thin plaque with and irregularly crenelated silhouettes is decorated on one side only. The décor consists of a curled dragon figure, the head of which partly coincides with the contour of the plaque. The design is executed in engraved lines, single and double, in a style close to late Western Chou bronze ornaments. The off-center perforation was drilled from both sides. Late Western or early Eastern Chou.
