Ardy:
I think what the link establishes is that this style of vase was made in Murano in the 1990's. I'm not sure it's made by the Seguso in your link. Alex, from ArtofVenice, would probably be in the best position to provide an answer to that question.
BTW, I'm not diminishing the value of your piece. I've always thought it was a very nice and well made piece. In fact between the two, I like your piece much more.
