Absolutely, Ross.
Me having a guess isn't any form of confirmation.
I'm going to be digging around that site you posted, for which I'm very grateful.
Unfortunately the Lithuanian glass I bought was around '04, a lot earlier than this studio seems to be,
according to that.
It was imported by a small business concentrating on new, quality, Eastern European goods. He couldn't tell me anything about the artists.
He did provide me with sticky plastic import labels and little cardboard certificates of authenticity which state that the glass is Vilniaus Stiklo Studija in Vilniaus, Lithuania.
So I suspect the studio might be older that its website says it is?
His import business, Baltic Impressions International, was established in '96.
I don't know if he's still going or not. I do know he moved in the later '00s.
None of my pieces were signed.
