It can't be the 1965 old-timers' game, because in 1965 Spahn wasn't an old-timer. And neither was Eddie Mathews, who's there with him. And if it's a regular game in 1965, why are Spahn and the Braves both in home uniforms? It could be a Braves-Cubs game, but that leaves the question of what Spahn's doing there (and who's the old guy on the right in what looks like Mack Jones's number 48?). Maybe it's a spring training game, and Spahn just decided to drive the four hours over to West Palm Beach to see his old teammates. It could be an old-timers' game a few years later, but if it was held by the Mets, then the Braves wouldn't be in home uniforms. And if it was held by the Braves, then Spahn wouldn't be a Met. It can't be the 1965 All-Star game, because Spahn wasn't on the team and wouldn't have been in uniform (and certainly not a home uniform--it was held in Minnesota).
