This single Vintage Scandinavian art glass wine glass was produced in Finland by Nuutajarvi between 1977 and 1993, which can be confirmed by the original plastic label on the foot. It's a simple wine glass with a thick stem. Inside the bottom of the stem is a single, ink like teardrop.
The glass measures 4 3/4" in height and just under 2 1/2" in diameter at the rim.
In excellent condition it has no chips, nicks or cracks.
