The first thing you’ll notice in this photo is how small the crowd is. It’s hard to tell because some people are partially or completely blocked by others, but I don’t think there are more than 100 fans shown here, and of course you can’t see all of left field, but there are probably fewer than 200 people in the bleachers on that day.
So exactly when was this photo taken? There are a few clues. The first is that all the teams are listed on the scoreboard in their pre-1953 cities, so it has to be 1952 or earlier.
