Here's a rarely seen and unlisted (in books and NIA website) Light Aqua CD 154 Vidrart (left) glass insulator from Argentina. Very bold embossing on the Vidrart side. Has circular scuff mark (seen in photo), tic mark on dome, base of inner skirt roughness, otherwise excellent. $50 plus shipping to the first email that says they will buy it.

On the right I'm offering a Light Sage Green Vidrart S.A./19 (front) E N T /Industria Argentina (reverse). Has amber thread behind main embossing, scattered light scuff marks, teeny ping, match head base rim flake with small nick next to it. $40 plus shipping to the first email that says they will buy it. Thanks!
