Unusual 3.5" with large blank white area where Carter's bw photo would normally be placed. Apparently a test piece from the production process with the name of the maker on the curl N.G. Slater. Extreme outer edge has some darker stain but just a little brown color showing up on top edges of a few letters of his last name and a couple of tiny marks on the "1980" date. Still displays quite well. Unsual and only example we know of.
