A stunning Swedish mid century art glass vase, circa 1950s-1960s. Many factories produced these similar pinstripe designs, so being unsigned it is likely by Sea Glasbruk, Glimma Glasbruk, Smlandshyttan, Skruf or Johansfors. (The signed versions are by Vicke Lindstrand for Kosta). It's shown on p117 of the 'Scandinavian Glass, Fire & Sea' book. 
The inner red glass has swirling twisted deep yellow stripes over, cased in clear glass. Bulbous lower part, slim pulled neck with flared rim (jack in the pulpit style). 26cm tall and suited to a single stem flower if used. Mouth blown and hand made in Sweden. Flat polished clear base, unsigned. 
Very good vintage condition for age (roughly 50-60 years old). Some tiny age related marks. No chips but a couple of bubbles from being blown - one noticeable one in the rim and a darker one in the neck (both shown), please see all photos. Nice displayable and collectable condition, I'd give it a 8/10.
