A stepped vase with a look of the 1920s-30s about it, bearing a folded rim. Ostensibly in a steel blue colour, but, curiously, turns a partially opalescent green when in direct sunlight.
It's 15cm/6" tall and 14cm/5.5" diameter, a polished pontil mark to the base alongside very heavy signs of wear.
I assume Northern Europe or Scandinavian manufacture, but I've exhausted my library for those parts of the world.
Any help gratefully received.
