Jay, my thought was, too, that according to the description from HA on the same card they auctioned, the size of that card seems correct at 10.25 x 13.25 inches, and it was never trimmed.
The way the ebay auction reads, the seller states that it was originally 14 x 11 inches, and even restored, was done so, but left smaller.
Like the homework you did, Jay, had that seller bothered to look on the HA auction history, he would have seen that this card was never the larger 14 x 11 to begin with.
So as you said, homework is key, when buying from the ebay folk.
And I will look to see what other stuff he's offering, too.
