I got this one about three or four years ago when I only had about 50 or 60 insulators and no price guide. It is a unique Star CD 133 in light blue. It is stuffed with snow and bubbles, has a small amber swirl, and the base is a distorted oval rather than the usual perfect circle base. I got this at a local garage sale for two dollars along with an aqua star keg, and a porcelain keg. It remains one of my favorite insulators.
