Baluster vase - Glass - Sixten Wennerstrand

Because of the dripping stripes I wonder if it was a design by Bent Orup, perhaps made by Johansfors, Sweden. These stripes are characteristic of this artist, who lived from 1916 to 1996. There is another name, which apparently gets mixed up online with Scandinavian vases featuring dripping stripes: Sixten Wennerstrand. The vase was bought in the 1980s.

The stripes are on the inside of the glass (not painted on the outside).
Condition: excellent, no cracks, no chips.
