Wondering if anyone has seen this piece or something similar before - or has any more information about this piece. It is signed Riihimäen Lasi Oy - A. Okkolin '46 - So I know it came out of the Riihimäki glass factory in Finland - and signed/designed by Aimo Okkolin. It's realtively huge(apple for scale) - almost 15" tall(about 37cm), 9" in diameter at the widest point, the glass is an inch thick at the rim. Weighs 17 pounds (7.7 kilos)! Has cut rose decoration all around. I can't find anything like it online so I don't think it was a regular production piece. Many thanks for any help or information.
