Catalogue entry no. 337 by Max Loehr:
337 Serrated Oblong Tablet
Light creamy brown, mildly translucent jade, smoothly polished. The tablet has a median crest on both sides. Its edges are beveled and notched like a sequence of fish tails. Far from the middle point the sequence is interrupted by a pair of hooks bending inward. The shorter portion beyond these hooks was either left in a fragmentary state or irregularly finished; one tip of the larger portion is broken off. The shorter end is perforated. Presumably Western Chou.
