This photo was found on the Cubs Archives Instagram page and sent to me recently by a reader.
The caption on the photo was:
Looking out at Wrigley Field from down the left field line, 1973.
That isn’t correct and I’m going to explain why and tell you the exact date this photo was taken. Here’s the full photo:

The first clue that tells us this isn’t 1973 are the railings you see in the box seats at the bottom of the photo. The lower deck at Wrigley Field was completely renovated between the end of the 1968 season and the beginning of the 1970 season, with those railings removed and the seats turned to face home plate.
