This is a stunning modernist vase, which I believe to be Scandinavian in origin, though have not found a definate identification.
The glas is a very thick flint glass, with a heavy base, with an etched/sandblasted upper body. In excellent condition with not a chip or crack to it, though a little minor wear to base commesurate with age.
The vase is 9 inches high, and the base itself is around 1 1/2 inches. Width to the top is 4 1/2 inches.
