1965-22 Cooperstown Plaque Postcards Baseball Forum

This set isn't nearly as easy as it is currently presented.  There are all kinds of variations throughout the years- manufacturers, back indicia, even some of the plaques have changed over the course of time.  I believe now the postcards come with a "year produced" on the back for re-printings.

There should be some kind of warning that this is only scratching the surface for how many different HOF plaque cards there actually are.
