In Sportscaster Series #09 I don't have any cards from print runs "B" and "C".
For the first print run, I only have 12 of the 24 cards. All of these were printed in Italy. Is there a blank print run from Japan?
I do have all 24 cards from print run "A", so I can at least compare them to the 12 cards in the first print run. Here are the three back variations I've seen.
9-16 Basketball - A Game for Giants - 'A' has different text
9-19 Alpine Skiing - The Two Garmisch Races, 1973 - 'A' has added results
9-24 Alpine Skiing - Use-Marie Morerod - 'A' has added text
I have a lot more from Series #10 so stay tuned for more variations.
