There’s no scoreboard visible here, just a Cubs game at Wrigley Field, and not in recent times. It’s a color photo, so it can’t be real old-timey. With no board, we’re going to have to look at other things in the photo to determine the date.
It would have been much more difficult to figure out exactly what this photo is showing if not for the helpful caption where I found it: “Wrigley Field - Cubs vs. Reds 1970.”
The link goes further and says this is May 1970.
The Cubs and Reds played a four-game series at Wrigley May 7-10, 1970.
