I'm with Ivo in saying generic Murano (although I prefer the term non attributable Murano). It's not that it's an inferior piece; it's more that it would be impossible from this photo to say Barbini and even difficult if you were holding it. A few companies made pieces like this. As I said, it's not to denigrate the piece, which I quite like personally. It's just I'd hate to be quoted as saying it's Barbini by someone selling it, which I think is probably a common reaction.
