For sale is a very handsome pair of Spiral Groovers CD 147.

They are both the [030] ein PATENTED (front) OCT. 8³ 1907. (rear)

Both pieces are in excellent condition with no appreciable flaws...let's call them VVNM!!

The Blue Aqua piece has a nice sized bubble just over the PATENTED embossing and other crudities from day-one

The Dark Yellow Green is full of Amber wisps, a tiny piece of potstone protruding the surface and other day-one anomalies.

The Green piece is listed in the Guide at $50-75, but with all it's interesting aspects and with the Blue companion, I'm asking $88 for the pair plus shipping.
