Hi, Dennis. Probably other people are like myself in admiring Livio Seguso, but being unable to put a price on his works. Livio did much of his animal work c. 1970, give or take a few years. I don't know about his relationship with gral glass of Germany. His work usually realizes good prices. The value varies widely, depending on the market. I am not an expert on Livio, so any value I would give would just be a guess. I can only say that it has good value. Sorry I could not provide better information. We have a couple of members who know more about Livio than I do. Perhaps they will read your message soon.
