Probably dating from the 1870s, this set of four wine glasses (each about 4 1/4 tall), is almost certainly Boston and Sandwich. The glass has the true flint glass ring; the shape is well documented in the Barlow and Kaiser books, with just this six-sided cut and polished stem, and the Greek Border cutting is also documented there. So: shape, cut stem, and cut decoration all match Boston and Sandwich, and the attribution seems reliable. Very difficult to find in a single piece, and much more difficult to find in a set like this.There is some slight variation in size, as expected for hand-blown items, but all are the same height and must be intended as wine glasses.
