1948 Hall of Fame
It's always interesting to read up on some history and notice how things were different back in the day. For example: Today if the Hall of Fame vote happens and nobody gets elected, then the baseball world awkwardly shrugs and waits to try again next year. Once upon a time, however, that wouldn't be good enough, as there were suggestions to create a run-off round of voting if no one gained 75% on the first try. As for voting like the Old-Timers Committee, there was no schedule and they met whenever they felt like it to nominate a player from long ago for immortalization.
Such rules were in place around 1948. Thankfully, the regular vote only needed one try to find worthy players to make plaques for, so Herb Pennock and Pie Traynor didn't need a re-do. It's funny when you see how strict and rigid the scheduling and standards are for voting today, then gaze into the past and see that there was a period where baseball was still ironing out the kinks in the process.
