Just about all of the players may have appeared on some kind of card but there are probably dozens for whom a signed card (genuine) simply does not exist. And what about executives, writers and broadcasters in the Hall?

Card collectors, I think, tend to be "set" focused, whereas autograph collectors don't usually think that way.
