Yes, its absolutely possible that a GPC would have two postmarks , happens sometimes. But unless Lou elected to drive up to Boston after a game in NYC and then return it would not have been possible for him to be in two places at the same time. And he had that "consecutive game" thing he was working on too so he would not have missed a game to go up to Boston ahead of the team which did not arrive there until the 9th.
