Hello Everyone and Happy New Year!
On the green filigrana piece, I dont think that little yellow Made In Italy label is not just an A. Toso label. I have had it on Seguso pieces, Fratelli Toso, Barovier and even Avem pieces before. I actually have 1 Avem Tutty Frutti holder, 2 Seguso figures, and 1 Barovier piece with the label in my possesion right now. Unless I am mistaken about all, I think this is just an import label. Maybe it was used between a particular date or a particular import company, but its very hard to say. At leat I am without an answer to that.
