Here are some more Venini labels which you can upload to the Gallery if you want.
If you want to try a chronological order I would suggest to do it that way:
Early fifties on a piece of ca. 1952:
Mid fifties to early sixties:
The Venini paper label that is already in your database.
Late sixties to seventies:
The Venini plastic label that is already in your database.

PS: Acid stamps are a different thing, they can even show up in the company of lables, the three line is ca. 1950-65 if authentic
