Hi, Keith.
No label, but I've got it noted that Ivo said it was Seguso. The piece does look like other Seguso pieces I have and have seen, but I'm not certain. The Galliano Ferro bubbles tend not to be quite so regular.
So, I think of it as probably Seguso, but it really doesn't matter too much to me as I like it and I'm not selling it.
