Vintage Game Used Football Question

[RaiderNationPDX]

Presuming the ball was used in the game and not just for presentation, then it is likely (though not guaranteed) that it was used for both offenses' respective possessions. Teams using their own balls started as far as I know in the mid-2000's after too many teams complained of the home team doctoring balls.

I will say though, that ball has the words "game ball" in quotes, with no specific player achievement other than "big game". Speaking personally, I wouldn't count on the ball actually having come straight off the field from that game...not saying it isn't a legit team presentation ball, but for me, I'd need more evidence that it was used in that game.
