Catalogue entry no. 378 by Max Loehr:
378 Plain Trapezoidal Plaque
Light green translucent jade with cream and russet spots. Above the concavely ground lower corner, the sides flare toward the crenelated upper edge. A straight, narrow flange projects from the slower edge of the plaque; it is much thinner than the plaque and is perforated twice. A larger, rather irregular, suspension hole is drilled below the central spur at the top. While superior to No. 377 in design and workmanship, this specimen has remained undecorated. Eastern Chou(?).
