I don't know the exact date but this style dates from 1936-1940. The brilliantly prolific Copier lived from 1901 to 1991.
The heavy crystal ball was once the top to a Leerdam decanter. The decanter is long gone but the ball looks very good set atop the vase, especially when gently rotated it multiplies the moving water effect. This was in my grandmother's home, and as a child (and frankly, as an adult) it fascinated me. I have always called it the fountain because of the wonderful regularly placed bubbles. I can't even imagine the skill that went into making this.
