Rare Venini & C. 'Soffiato' vase, Jewel Glass label

Rare Venini & C. "Soffiato" vase.
Rare soffiato vase, the Venini label has gone off on the underside.
On the front is a "Jewel Glass - Trade Mark - Made in Italy" label.
The only reference I found for the Jewel Glass label ist this link:
Wright20.com - Carlo Scarpa Corrosi vase, Venini Italy, 1936
'Jewel Glass was an important retailer and importer of pre-war Italian glass.
Signed with foil importer’s label.' (Wright20.com)
