I have a number of saved searches on eBay that I periodically check up on. One of my favorites is "Georgian" under the category of antiques/decorative arts/glass/stemware.
Even if I could find or afford a whole set of Georgian glassware, I wouldn't want it. I'm buying a glass or two at a time here and there and I like that my "set" isn't matched. I imagine a dinner party where I can use all my different glasses, some for wine, water or perhaps sherry (which is actually really a nice little beverage).
The listings for the pair of etched glasses and for the single rummer are two current favorites. Their price might climb out of my range. If so, I don't continue to bid. But sometimes I get lucky. Stick with it. Searching for these old pieces takes patience if you don't have a fortune to spend. But how it would be worth it!
