(“Old” in my world meant they played before 1966, when I started following baseball.) I started playing APBA in 1967, and within a few years I was buying (or, rather, my parents were buying for me) great teams of the past or full seasons from the early ’60s that APBA was closing out.
When I was an adolescent baseball fan in the late 1960s and early ’70s, the primary way I learned about “old” baseball players was through the APBA baseball game.
