Exhibit Antiques has dated this piece to the Georgian era.
A fine 18th-century engraved light baluster wine glass dating to c.1735–40.
The bowl is supported by a small shoulder baluster knop above a large baluster basal knop. Conical foot with a snapped pontil.

A particularly elegant example of a light baluster form, retaining the strong influence of early 18th-century decorative engraving whilst displaying the increasingly refined proportions associated with the period.
