Hi Adam P,
Thank you for the photos!
I havent seen those before. I do have 2 pieces by Gaspari, but they arent abstract pieces at all. One is a plate with fish inside, which I think was made along with Barbini and the other a large bird, both pieces being figural. I'll have to check on him for sure, specially if the 'Polychrome Stones' or 'Sasso Policromo' are rare pieces!
I also didnt want to just say it was Murano because it was in with a lot of Scandinavian and Murano combined. Mine is a bit different to your photos, so it might not be Gaspari... Do you guys think this topic should be moved to the general board? I guess its not really a paperweight and more of a sculpture.... If you guys think that is a better bet to get info on this, feel free to change it.
Thank again Adam!
