Quick but hopefully straightforward question - I have seen the late 60s O-Pee-Chee Posters insert labeled as both 1967 (Beckett seems to list them as
1967 OPC "Paper Inserts") whereas other places like TCDB list them as
1968 OPC Posters
I am slightly unsure if Beckett's Paper Inserts listing is supposed to be Posters or not - the checklist appears to be the same players but in a different order. But they don't seem to have any Posters insert in the 1968 OPC set, and the 1967 Paper Inserts set description linked above references that there is confusing if these belong to 1967 or 1968, so I am assuming that the "Paper Inserts" are supposed to be the Posters
Is there a consensus of which year these belong to?
