Pictured above is one scanner bed full of these minis. The full set takes multiple scans.
There are 72 cards in the set. These were special cards that were included in the factory boxes. Collectors would also find one motion card per pack off the shelf. Each card measures 2" x 2.5" in size.
The front of the card is a 'motion' (like Sportflics) that would change from "World Series Trivia" or "World Series Q&A" to the year the card focuses on (in this case, 1932):

On the back, the collector finds either a tidbit of trivia (on the "Trivia" cards or a question to be answered (on the "Q&A" cards):

If you were to ask anyone that either collected these in the 90's or has since discovered them and held them in their collection for any length of time, the first thing that likely comes to mind is the fact that these little cards are stiff as boards and bend like nobody's business.
Over time, for whatever reason, the 'stuff' that binds everything together on these cards appears to shrink or tighten. The cards end up bowing in the middle and will not lay flat. In fact, to get the scans, I had to press down on the lid of my scanner. What a weird thing to happen, eh?
