A very fine wine glass, having a large bell bowl on a colour twist stem ,which has an inner white core with a cobalt exterior,( a very rare feature) with a pair of white threads around, all on a plain conical foot.

Height 6 1/2 ins 16.5 cm

The inner column is very unusual with the core being white which is covered in cobalt blue and twisted slightly during construction to reveal the white core, A very rare feature but not unique,

A superb large glass in perfect original condition
