Thanks David. That looks like a great book, and I really need to get more!
The real reason I was excited to see this is if it could be firmly attributed to Barovier and Toso (or another well known maker), that would prove that J.I. Co did import from at least one of the famous glass houses. J.I. Co has a reputation for importing "generic" Murano glass, but a piece like this looks very nice to me, and considering how the auction is going, I guess I'm not the only one who likes it!
