The Salviati companies are complicated. I no longer try to separate their 19th Century pieces from Barovier, since the Barovier brothers worked for, then bought the company. Salviati & C. becomes synomous with Artisti Barovier (scream!). I get most confused because of the parallel Salviati enterprises, Pauly, and CVM, (which many companies made glass for). I have to remind myself that the companies were in business to make money and not to make it easier for me to sort through. I've seen the same pieces listed as Salviati, Barovier, and CVM -- perhaps all true.
I am glad that Aldo Bova wrote you. At least you have a good idea of the time of the catalog. I had tried to turn your dancer into a Luciano Gaspari piece with its graceful lines. But the time was all wrong. I think we can safely say that the form is all wrong, too. My imagination was working overtime.
I read recently that Salviati closed, but I don't know if it is the truth. I knew the French had bought them several years ago, but it was the last I heard. I have not paid much attention to them recently. Their glass became too conventional for my taste.
