Thanks, SFMS.

That is some great, although somewhat confusing (for me) information. I always thought cream and gray backs were one of the same, just different names people, over the years used to describe them.

Reading this, and with all the cards I own, I do wish I had a copy or 2 to share/be a part of this unique, hard to obtain subset if you will.
