The underside retains an original ink stamp reading:

HAND MADE POTTERY
NATURAL BRIDGE
VA

There is also a partially legible curved maker/pottery marking that appears to begin with “JAMES…”. The remainder of the mark is worn and has not been positively identified, so no specific maker is being attributed.

Approximately 6 1/2" diameter × 1 3/4" high

Unusual ring-form design intended for arranging flowers and greenery. Attractive piece of vintage Virginia regional/studio pottery and a great addition to a flower-frog, art pottery, or American studio pottery collection.  No flaws in Outstanding condition.  Please ask questions if you might have.
