You got that one! Good, I'm glad it went to someone I know! I was following it, and nearly bid - in fact, once it was over I think I was cursing myself for not having bid! I'm glad you got it.
I have Gardner's book with all the Steuben line drawings from the library right now. Interestingly, the line number isn't shown with the other vases, but it is shown in a separate catalog section where a bunch of decorations are illustrated. The one there is wider, but same vase, and the engraving on it happens to be the same: "ENGRAVED." All the others shown have a name ("Decoration - RENWICK"), but this one is simply, "Decoration - ENGRAVED."
Nice find!
