This set of 36 postcards measures 3 1/2" by 5 1/2" and showcases the Brooklyn Dodgers. On a blue background, the horizontal fronts feature color drawings by Susan Rini. There were three subsets in the first series, with 12 cards each. The cards are numbered on the back as "X of 12." Suffixes (A, B, and C) have been arbitrarily assigned to the card numbers below to distinguish between the three subsets.
