I have been receiving scans from from a person who inherited a number of these from a Topps employee and has been kind enough to send me scans. The checklist has grown to 14 cards:
Banks/Stottlemyre
Clendenon/Kaline
Flood/Skowron
J.R. Hart/Mantle
Koufax/Yastrzemski
Roseboro/Richardson
Marichal/Rollins
Grant/Callison
Stargell/Mantilla
Mays/Conigliaro
Killebrew/Torre
Frank Robinson/McMillan
Hansen/Cardenas
Santo/Battey
and I have scans of them all plus some other stuff on the set over at my blog:

I've sent the link to Don Fluckinger at the Standard Catalog as 4 of these were previously unknown. I do not know what the owner ultimately intends to do with them and he is not looking to sell or consign them at this time. I will not be passing along requests to him either so please respect his wishes for privacy.
Any comments you have for
me though, fire away, especially on my theory of how many cards might be in the set (my educated guess is 20, if you were wondering).
