These flip books were issued in 1937 and 1938. The books measured 2 inches by 3 inches and were designed to cash in on the penny arcade craze that was popular at the time.
Each of the thirteen players featured in this release have two flip books comprising of two halves. When viewed back to back, both halves completed a specific game action. In the case of Luke Appling, the flip books feature him setting up for a double play. While these seem routine today, any game action would have had kids flipping out in the late thirties.
While television had been commercially available since the 1920s, television sets wouldn't become commonplace until after WWII. The first regular broadcasting wouldn't come until a decade later, in 1948. The first baseball game wouldn't be televised until August 11, 1951, when a station in New York showed the Boston Braves beat the Brooklyn Dodgers by a score of 8-1.
Out of the thirteen subjects, the White Sox have one player.

These flip books are a nice relic of the past. I can remember flip books still being produced when I was a kid, but I haven't seen them around in years. I even remember making a flip book in my younger days. I'm sure it was about baseball.
Who knows how many kids were inspired to be animators from this set. I would imagine that there were at least a few. In today's world of non-stop sports action on television, these seem very outdated. The coolness factor never really goes away from a product like this though.
