Loaded with dozens to hundreds of each player represented the first three rows run alphabetically from Seaver to Yaz the last two rows appear to be from an earlier box as they run from Eckersley through Bob Gibson. HEAVY duplication but that's not a bad thing when you're talking 8 1972 Yastrzemskis, or a couple dozen 1978 Fisks, or even a few Garvey rookies. The players in the box include HOF'ers:

Tom Seaver
Ozzie Smith
Willie Stargell
Bruce Sutter
Don Sutton
Alan Trammell
Dave Winfield
Carl Yastrzemski
Bob Gibson
Rollie FIngers
Dennis Eckersley
Carlton Fisk

The non-HOF'ers are still stars like Garvey, Strawberry, Staub, Stieb (a better pitcher than Jack Morris!), Whitaker etc.
