A vintage German glass vase designed for the Rosenthal Studio Line - we think this is a 1980s piece, possibly later.
It's very modern, with a simple, geometric form and split into an opaque, black half and a clear one. The glass is very thick, this is a substantial piece!
The vase is 25 cm (10") high and in good vintage condition. There is some light wear and a little calcium deposit to the inside from use. There is a tiny fleabite to the top edge and a small surface scratch (pictured.)
