This is very very very weird. The blank is called "Elefantino" and is produced by Stiver in Italy. Now this would be the first time we see non-Gordiola glass decorated by Royo - we do not even know where he produced, just that it was in Cataluña. Stiver set up production in the mid 1960s - it is believed the Animaletti series is one of the oldest. As we still have no concept of when Royo worked, we now know it must have been at least into the late sixties....
