Vintage gold flake bullicante Murano art glass pitcher w/ original import label

Lovely bullicante Murano hand-blown glass pitcher with gold flakes or cordonato d'oro  cased inside the glass. It's a large piece, about 9 1/2' tall. It's in excellent condition without damage.

This has the original importers label as shown, though it doesn't appear to be signed that we could see. We've been told that this type of work is typically Barovier Toso, but we're not terribly familiar with Murano glass, and don't know much else about it!
