I have a listing, circa 1993, that was put out by the Italian Trade Assoc. of approx: 90 companies in Italy who produced glass and giftwares with their contact info and a short list of the type items they produced. If anyone is interested in this,,I hesitate to dispose of it. I'd be willing to send it to anyone for $10 + postage. It has many glass companies listed , as an example, Alfredo Barbini SRL,Francesco Barbini, Fratelli Barbini, Silvio Barbini, I had no idea there were at least 4 Barbini glass manufacturers at different addresses. , as well as several Fuga companies. I had gotten this from the Italian trade assoc. when I made a trip to Italy in 1993. total of 16 pages with 6 names on a page. I wonder how many of these are still in business.
I also have an old Sam Herman brochure, circa 1981, and a couple of Midsummers Glassblowers brochures, circa 1980's listed on e-bay at present as well, if anyone is interested.
