A fine and unusual antique English drinking glass of Jacobite significance. The round funnel bowl is beautifully engraved with a rose, a bud to the right, a butterfly, and foliage. The stem is of the double series air twist type, quite uncommon because of the configuration of a pair of mercury corkscrews outside of a central cable. Conical foot with a rough snapped pontil. Lead metal with good color, striations, and tooling marks.
The condition is excellent, with no chips, cracks, or restoration. The specks in the photos are dust, not air bubbles. The height of this wonderful example is 6 1/8", with a bowl diameter of 2 1/2" and a foot diameter of 2 3/4".
