After looking at the bull several times I have to agree with Javier (Sorry Anita). The bull's color reminds me of Livio Seguso and also the style. It may even be made in Germany for Gral Glashutte, but without seeing another with a label on it, I couldn't say for sure. Very nice bull. Javier mentions he has seen some with Salviati labels so that also leads me to believe Livio made them for Salviati. I have noticed that a lot of Livio's animals designs from Salviati and Gral can look the same. If anything, I would place my bets on Livio Seguso as the glass master.
