I've come across a possible variation regarding the inset photo of Denny McLain on 1969 checklist card #57, which features McLain's head lined up in different positions within the inset circle. You can tell by the amount of collar showing.
On cards where there is only part of the collar visible, the back copyright information is printed with or without a dot after the 'S' in 'U.S.A.' The other version shows more of a full collar, in which the dot on reverse in always present.
It seems similar to the 1968 checklists featuring Frank Robinson and Ken Holtzman.
What do you think?
