Take it up with GRIS. lol WTF is up with all the butthurt in this thread?
I did some research and happened to be wrong. The image is quite often attributed to Ten Cent Beer Night and I visited neither stadium in 1974 so had no first hand knowledge of stadium appearance. I tried to confirm by looking at historical images of the parks from that year but could not be sure.
Dude jumps in with a passive/aggressive, non-informative comment and now others, such as you, are piling on. So the first response I get is a flippant, non-informative, worthless response.
Now that I look at the full post, I see that others before him posted some actual sources, with actual information which is a great thing. But that guy just decided to be a flippant dick. If he had laid out some information and sources he would have been much more helpful.
