Hi,
I'm referring to your one.
I have some pieces by Venini made between end '50s and '60s and this is my feeling:
a) Colours and thickness are similar to the famous vase designed by Licata at the mid of '50s, but it features also a band of yellow murrine in the center area (there were two incamos and not just one)
b) The design is more similar to some pieces made during '60s, but they are much more thin and the point of connection of the two pieces attached by incalmo is more evident.
Obviously to be more sure you shuld have the different glassworks all in your hands to have the right information about thickness, weight, colours.
I suppose that, as usual in Murano, somebody has seen the Venini piece and made something in similar style, may be at the same time or later.
Sincerely
Alex
