Here are a pair of CD 121's for your perusal. On the left is an EIN [020] (F-Skirt) {Diamond} SB in royal purple. Condition is excellent with only the base sliver that shows from the rear. Displays perfect from the front where several little bubbles play peek-a-boo inside and outside the diamond. Click on View Original, above, for more detail. On the right is an EIN [020] (F-Skirt) (Arc) NEW ENG.TEL.& TEL.CO. SB in aqua with light amber wisps visible in the rear. Tiny scattered champagne bubbles sparkle when backlit. Condition is used. 8^) An open base bubble in the front is obvious, tiny nibbles to the wire ridges at the right mold line are less so, and some surface scratches here and there round out the damage report. Sounds worse than it is. Take this colorful pair for $40 plus postage.
