Catalogue entry no. 508 by Max Loehr:
508 Hinged Pair of Plaques
Very light green translucent jade with ivory-colored calcified spots. The two plaques and the oval ring linking them were carved from one tablet which, to judge from the finished state, was of uneven thickness. The flawlessly designed plaques represent the lively silhouettes of two creatures mounted on rectangular slotted frames: above is a feline with crest and long tail; below, a bird with turned head and enormously heavy tail feathers. A few exquisitely drawn linear motifs are engraved on the bodies. Only the oval ring has fully retained the original glossy polish. Late Eastern Chou.
