When you get your hands on a group of glass as a single purchase it makes no odds at all they came together, this i have learnt the hard way searching similar patterns for hours on end, i found a pattern yesterday with a bohemian sticker label, i have a set of these glasses i thought were Stuart Glengarry, spent 3 days looking them up, when somewhere in Bohemia they copied the pattern, it's a nightmare, no i will only look up signed glass.
