At least we've got improved checklists:
Cubs
1) 1B Frank Chance
2) P Orval Overall
3) SS Joe Tinker
4) OF Jimmy Sheckard (or possibly Steinfeldt or even a misspelled Schulte?) (next to #3 Tinker)
5/6) OF Solly Hofman and C Johnny Kling (need better scans to determine #)

Athletics:
1) 1B Harry Davis
2/3?) 2B Eddie Collins
2/3?)
4) 3B Frank Baker
5) OF Topsy Hartsel
6) ?

So between both teams we have C, 1B, 2B, SS, 3B, 3 OFs, and a P. Still missing a couple to call it complete, since presumably there are an equal number; I'm guessing two more Athletics for #1-6 (if Sheckard is #4) to match the Cubs.
