Catalogue entry no. 335 by Max Loehr:
335 Ornamental Plaque
A warm grayish white and light brown, strongly translucent jade plaque, apparently fashioned from the section of a broken disk. Adapted to the given contour and surface is a design—on one side only— in single and double engraved lines representing a dragon overlapped by a bird. Neither of these zoomorphs is shown complete; of the dragon we see only the head. The piece is perforated in the middle under the bird’s convolute beak. Late Western or early Eastern Chou.
