Lol I know what you mean Kane, such a shame!
Sandy, thanks for posting your pics, I've seen quite a few in that style too. I'm not sure, but I think that label might have been one of the generic red ones, I had a look through the Murano labels section on here though and couldn't spot it.
I was hoping if these signatures could be verified, then it might confirm if these designs were Seguso Vetri d'Arte. It's never that simple though is it? I guess we will have to wait for Marc Heiremans book to come out. Another three years apparently, I can't wait!!!
