Space age vase – white opaline glass art piece

Glass space age vase

Little is known to me about this beautifully designed vase. The model immediately seemed very familiar to me. Still, I can't find a second copy on the internet.
It is made of thick white opaline glass, and luckily it is in very good condition. Some small scratches, and in the glass are some tiny air bubbles, very difficult to see.
