Certainly one of the more unusual pieces with such a label. Perhaps you'll be lucky and somebody will recognize it. Have you checked the Murano label library on GMB? I can't see the label in the photograph clearly enough to tell for certain, but it looks like it might be file 71, 88, or 117 in that list. They are all variants of the one label.
My take on these labels is that they're never going to provide you with enough information to take you any further than saying it's Murano. If you're a collector, I'm not sure this is much of a problem because presumably we're collecting glass not labels. What's important to me is deciding whether I like it, and I find out by looking at the piece itself. For me I'm looking for a combination of form, colour and technique. It's not even related to cost. I love a huge dish, maker unknown, I bought for $8.99 almost as much as my Barbini Pezzato vase, which cost a little more.
If you're a seller, then I see the difficulty these labels cause. I understand that buyers want their purchases to be from one of the big makers. Even then, most of the houses also produced tourist glass to make a profit. I'm not sure there are many companies that have made a profit from the sale of exhibition standard pieces. The irony is that at present there are quite a few pieces from good companies, Fratelli Toso and Seguso, for example, surfacing without labels at very reasonable prices.
I think I suggested to Anita (TxSilver) either here or in an email that we should replace "generic," which is term that turns people off as quickly as telling them that their kid is average, with something like PNA, Piece Non Attributable. Then we could focus on the glass itself.
My, I've had my little rant for the evening. See what happens when there's nothing on the PVR?
BTW, I think this is a very nice piece. Solid, nice colour and flow, good use of bullicante and gold. I'd love it on one of my shelve,k whoever made it.
