Michael Bang was the designer of the series this vase belongs to. The series is called Atlantis and was designed for Holmegaard Glassworks in Denmark in 1980.
This particular vase is ovoid in shape and features a deep blue rim with hand applied abstract design in inky blue black shades over white opal glass cased in clear glass. Each piece from this series is unique from the next but echoes each other in design. No two pieces are identical.
There is no damage to this lovely piece.
The vase is 150mm tall and 140mm in diameter. It is not signed but is unmistakably Holmegaard.
