I'm not a super sleuth. I don't know how some people on here find the information they do so quickly.
But doing some basic research on this set, a checklist may be difficult to assemble. To begin with, the set contained either a 1909-11 T206 card or a Historic Original Art Card encased with a cut signature of the player. I'm guessing the black back was some sort of parallel, but the actual "base" set here had 88 cards, from what I saw.
I only saw one link on a forum for a checklist, and it no longer works (was supposed to go to the Historic Autographs website). I also see some info for a set based on 1933 Goudey cards (same company, same year).
I'm going to be a parrott here and echo Dan, but yeah, whoever submitted this please let us know where this came from, because there doesn't seem to be a solid lead on Google anywhere. To wrap things full circle, I did offer a disclaimer that I suck at researching things, so maybe I'm missing something :)
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
