Catalogue entry no. 554a by Max Loehr:
554 Pair of Pigs
Mottled dark green and buff jade, with traces of cinnabar. The figures are carved from prismatic pieces slightly higher than wide. Heads and backs are rounded off; the bottoms remain flat and sharp-cornered. The ears are carved out in low relief, while the limbs are incised with sloping cuts. Three creases above the blunt snout are indicated by simple grooves. The eyes are indistinctly incised. A short perforated ridge at the back represents the tail. Another perforation is drilled transversely below the snout. Probably Western Han.
