The green one when underlit it borders a yellow green and it has a few bubbles throughout and also over an inch of dome glass. The dome has a neat milk/steam halo circling the dome and trails off down into the rear skirt. It has a small burst bubble on upper wire ridge there from day one and a rub on right crown otherwise mint. The Blue/Aqua has some fine milk swirls wandering around the dome and crown areas. It has a couple flat sheers at right mold line 1/2 inch long & couple dome pecks, rest is mint. Asking $45.00 U.S. + shipping and I accept PayPal using family/gift mode. First email gets it.
