Boston Sandwich Glass and dating to the c1850's. Fantastic for display and about 8 1/8" tall and 3 3/8" diameter across the bottle. Mounted on a gilt metal relief base with profiles and fronds with a base about 3 7/8" diameter, which obscures a chip that remains hidden unless flipped over. Very fine quality and other than the hidden chip, it is in excellent condition and wonderful to display. Very fine polished rounds all around the bottle....the cutting reveals the white enamel under the cobalt which is cut to clear.
