Yepper, a claw foot. Is this pottery or metal?
What is fascinating is the origins of the claw foot and claw/ball design. Origins were from Chinese/Japanese (?) and it is even argued that the origins are 1) the claw of a dragon holding the pearl of wisdom and/or 2) the claw of a crane holding onto a river stone. The crane stand stands watching over her nest attentively while resting on one leg. The raised/tucked leg holds the stone and should the crane fall asleep...the claw would relax/fall and the crane would quickly awaken to keep watch over the young.
Irregardless of origin, the use of feet on items has fascinated collectors for centuries.
