Ive started collecting Victorian wine glasses, but they have to be over 6 inches tall, mine date from 1860 to 80 about 12 are dated, in my opinion glass cutting engraving and blowing at it's best, they look great all displayed together and the work for the price i'm paying is stupid, i have 64 so far all different patterns and cutting some dated and impossible i would think to pin down a maker.
Very nice glass by the way and i would not part with it.
