I can't remember where I read it now, but Royo worked into the 80s. That the enamel work is inferior indicates that there is a good chance it was Royo. Enamel on his pieces are thinner and generally less attractive than the ones decorated by Genis Cirera. I have the feeling that Royo was a bit younger than Cirera and that both did the bulk of their work in Barcelona using blanks bought from Gordiola. It is difficult to find any information on Royo, however, so I am just guessing based on when they stopped making glass.
It is apparent that the elephant is molded. It may be that the mold was copied by Stiver or sold to Stiver. The color of the elephant looks very much like Gordiola. I have seen a few other molds pass around the European countries, so it wouldn't be unusual for both places to have the same design.
