Cards? What makes you think I only picked up cards at the Expo? There was a dealer that had miscellaneous items from the last season the Mets played at Shea.
Such as a ticket brochure.
A Dunkin' Donuts card.
A souvenir cup.
And a pocket schedule. All great items for a Mets fan that has an international border between himself and NYC.
But I didn't just get a Mets item for the non-cards collection. I also grabbed this pocket schedule for the inaugural Senators season. Although you kinda want to forget a season where they won a grand total of one game on the road.
