Catalogue entry no. 438a by Max Loehr:
438 Pair of Tiger Slabs
Highly polished jade, the color of tortoise-shell. The uncouth bulk of the heads and bodies contrasts curiously with the highly ornate and formalistic execution. The faces, the surfaces of which are left plain, contrast with the diverse texture of the bodies, which are covered with plastic curls; the shoulders and hind-quarters, filled with incised, interlocked T -hooks; and the tails, marked by median lines and concentric curves. Striated ropes border the mouths and frame the jaws. The outline of the lower jaws exhibits the axe-shape observed before (e.g. Nos. 427 and 432), a shape that is very pronounced here on account of the inward-curved fangs. Jaws, forelegs, and hindlegs form a continuous chain of curlicues, set off from the bodies by openwork. The tails are similarly separated from the haunches by a narrow crescent-shaped slot. Each slab perforated at top center. Late Eastern Chou.
