Italian hand blown Glass vase in the manner of Fulvio Bianconi

This beautiful vase was purchased out of a wonderful estate. We took the time to send images to the heirs of Fulvio Bianconi to try and get it authenticated. We were told by them that while there are many drawings of many similar styles, they do mot believe that Bianconi blew this vase himself, but it was very possibly made in his studio by another glass blower. Nevertheless it is a heavy beautiful vase.
Very good with bubbles in the glass and some scratches to the base and very minor flea bites.
