Retro Vintage Modernist Green "Alien" Ball Vase.
This unusual, wonderful quality vase has three layers of glass, the outside being clear with a green center and white inner. The windows that can be seen have been cut through from the inside.
On very colse inspection here is one tiny <1mm fleabite to the bowl, however this is insignificant.
The vase measures 15cm diameter and 13cm high.
