The Cubs and Sox linescores were both in the middle of the board and now its on the bottom.
The center field section went from tarped to untarped to the current Juniper Bushes.
The railing in the picture indicates to me that it is the newer dugout and not the old dugout. At least I do not remember any railings in the old dugout.
My guess is that the picture was taken between 1979 and 1983. | 
This is photo I took years ago during the off season.
