I was wondering if maybe the reason there's no information around on this glass is because it's actually a more recent glass - like post World War II or even 1960's or early 70's. The early glasses I've seen have fancier stems and the stem on this glass seems awfully plain. The workmanship on the bowl is excellent but for all I know they have computer controlled lasers that can make this glass in about 30 seconds. And there's a lot of cameo glass around. If you have 50 bucks in your pocket, you can buy a Galle vase that's guaranteed to be genuine! In my opinion, it'll be a pretty hideous vase but then "beauty is in the eye of the beholder", if you'll pardon the tired old cliche.
