Yes, yes I know, watermarks all over this photo. This is considered “fair use,” I’m not trying to sell this photo, just sleuth it.
That said, let’s have a look at what we see.
First, the Chinese elms are on the steps up toward center field and there’s no clock on the board. That makes this one within the first few years of the iconic bleachers and scoreboard.
The clock was added in mid-1941, so this photo has to be from between late 1937 and early 1941.
The clue that’s the most useful here is what appears at the bottom of the board.
