Newest 4 wine glasses from Finland - 70s

Here I newest have a set of 4 handmade designer glasses from the 70s.
The glasses are minimally different (orientation, foot shape).
Height: about 15 cm
There is a sticker on each foot:
Lasinpuhaltamo
Lasinpuhallus Aleljee Rajalahti Oy
Töysä - Finland

The feet are 3-piece, 2-colored, and have the form of leaves.
It could also be fish fins, I'm not sure.
