At first glance, this CD 121 Am. Tel & Tel. Co. Toll looks pretty ordinary and just a boring old aqua. But a closer look will reveal that there are swirls of teal in the dome, as well as a few faint amber streaks as well. The teal swirls are a darker blue than the surrounding glass, and backlighting brings them out nicely. Definitely an unusual piece. Elmer style with blots & dots on the rear skirt and a ring at the top of the pinhole. Good condition overall with a small upper wire groove chip at the left mold seam, a very small lower wire ridge flake in back, and a small base flake in back as well. Asking $40 plus shipping.
