This was another addition to my 20's and 30's collection. It has orange, lime green, pale aqua blue/green and lavender/grey in it, all in a creamish mottled background full of masses of bubbles and aventurine splashes. I think it is colour code 396?
It's slightly wonky and the size is not 5 1/2" or 7" but actually 6 1/8" diameter. Height is 2 3/4".
