Looks like the concensus is that the Originals set is NNO & 1/1 that is comprised of the 25 subject reprint set plus an unknown amount of additional unknown subjects.
The Sell Sheet does allude to it being larger than the 25 reprint set but doesn't provide a checklist. It doesn't appear that a compete checklist was ever put out by Topps directly or indirectly through the likes of Beckett, Cardboard Connection, etc. So at this point it seems impossible to prove if any of the additional subjects were made by one of the artists with extra stock they may have had left over or not.
I found some of these additional subjects online doing an ebay search. In addition to Todd Frazier, I found: Joc Pederson - Dodgers, David Price - Red Sox, Goose Gossage - Yankees, Yoenis Cespedes - Mets, Rod Carew - Angels.
Thanks to each of you for your input. I will submit this information via the inaccuracies link for this set & we should get this information corrected shortly.
