Broken all around and at back; badly battered.

Attachment in high relief, originally attached to a fairly large vase.

A trace of the inner wall is visible, nearly flat, with clear wheel marks. Bearded, frontal head with beetling brow, thick curly beard cut fairly short. Thick hair or headdress over forehead, possibly a lion skin. Pierced on left with a skewer for firing. Shiny black glaze, mostly missing.
