I don't think the vases are the same... similar, yes, but same, no...
Sergio, your vase has got a ZBS label which was used (according to Mark Hill's Hi Sklo Lo Sklo
) between the 1960s and 1980s. Miloslav Klinger was head designer at Zelezny Brod until 1982. I suppose there is a good chance it was designed by him. When exactly, and what is the pattern number, is a whole other question.
By the way, I think it's a lovely vase. :hi:
