Your are spot on. Part of the section on imagery analysis is intended to show how to "pick apart" a photo for commonly overlooked details that can help date a photo, thus the uniform in question. In some cases, I have been able to ID a date by looking at the details on the scoreboard in the background. These will often show what teams are playing and who the starting pitchers were. Much of this historical data is available on line.
You can also data a picture to a period if you understand when particular manufactuer's uniforms featured things like hole vented vs cotton elastic croch and underarm areas.
Great Comment..
Thanks,
