(OK, get in line anyone who disputes this....)
Yes, this is good, a fine piece of design, made at the Rosice factory of Sklo Union. Date of introduction @1960-61
These are known in un-coloured glass,
and: a non-uranium green, dark green, aubergine, amethyst, turquoise, sky-blue, cobalt, amber, citrine, and many daily variants.... and two sizes, little, 150 mm, big, 200mm.
A nice find.
