One additional item regarding the mount.

I believe the mount is real, but this fact is useless when it comes to authentication. Williamson was a prolific photographer and a prolific creator of cdv's, so procuring a genuine Williamson mount is simple. Procuring a genuine Williamson mount with a photo the same size as the one on the Brooklyn cdv would be a bit more difficult, as this is not the normal image size that Williamson put on his cdv's. The normal size image would be the one that used to be on this mount, as evidenced by the residue that shows both above and below the image (especially below), from the placement of a previous photo. As prolific of a photographer as Williamson was, why wouldn't he simply use a new mount? I'm sure he had plenty of them.

You can google 'williamson brooklyn' images, and you will ONLY find cdv images of the larger size. Williamson had access to the original negative and could have shown more of the baseball players and still used his vignette process, AND produced his normal image-size. But he didn't. Curious. I'll create an example and post it here later.

Yet another reason to test the binder - a bit from just above 'Williamson', and a bit from a corner of the image. Simple process, and removes more doubt.
