This Base Embossed American Insulator Company CD 126.4 [020] is a BEAUTY!! It is a LIGHT BLUE and has an area of Milk in the dome and milk swirl in the base surrounding a bubble. A teensy base flake-ette at the base edge is it for issues. Some interesting bubbling also.

I'm asking $65 for this handsome beast plus shipping More pictures available if you are interested.
