I responded to Matt over at the blog and he could be on to something:

"Comparing to Look n See, which is the nearest set in time with these dimensions, suggests a possible print array of 11 x 11 for 121 cards the size of a single Red Back. If you take 20 possible Teams and Connie Macks, that takes 40 slots and we add 52 to get to 92, so some would be double printed so there is room."

Intriguingly, Scoop, issued after Look n See, may have been produced in a 13 x 12 array (156 cards), which if you double print all the Red Backs (104 slots) and single print the Connie Macks and Teams (40) and add it all up, you get to 144 with 12 slots left over, so maybe a half dozen Red Back panels were triple prints.

I have no data on double prints in the Red Backs but I know there are some thoughts out there on how the short prints work in the Connie Macks and Teams. The cards were die cut (except Teams), with Red Backs being rounded on the corners and Connie Macks scored to allow the punchout of the player to work. That would probably play into how the sheets were arranged as those are two different processes.

Blue Backs and Major League All Stars could also have been produced on the same sheet then but without the Teams, which do not come with blue reverses.
