I really like this set:
http://www.psacard.com/PSASetRegistr...on.aspx?c=3658 for a much easier challenge that still includes a bunch of great players. And only the Hutson and Hein are.... "contrived" rookies.
So who would be the tough HOFers in a real earliest item HOF set? And the set wouldn't be all cards, right? Probably about 20 matchbooks? And how many photos? Would anyone be impossible? George Trafton?
