Catalogue entry no. 193 by Max Loehr:
193 Axe-shaped Tablet
Mottled green, gray, and black jade with whitish veins. Thin and flat, evenly smoothed tablet with tapering sides and rounded off shoulders. Slightly curved, slanting, blunt edge. The perforation is not circular; its wall is uneven as if it had been chiseled out rather than drilled. Western Chou(?).
