This shows the Classic Murano figurine head with the casque hair position. The bowl has been waved to hot attach the two busts that are connected to the bowls also with the arms in a figurehead position.
Bowl is in clear and rest in black glass heavily iridised. Hairs have gold leaf applied.

The attribution to Ercole Barovier is indirect as comes from the same lot of the other Ercole Barovier pieces.
Very rare with the nude body (typical of figurehead).

Owner called it Coppa Moresca.
