I recently watched a video of the complete 7th game of the 1965 World Series. Unlike the films of the 1950s, it has plenty of shots from the center field camera. Very instructive to see that in 1965 the umpires called strikes on pitches across the chest, several inches higher than the top of even today's "higher" zone.

Interesting also that checked swings that today would be obvious strikes were routinely called balls and not even appealed to the base umpires. In those days, you really had to take a cut.
