Old OLD skool football vids?

I've done a couple of searches, can't find anything.

Any of you know where I could see some video (if there is any) of what Football looked like pre-forward pass rules coming in in 1906 (think it was then). Not sure they even had recorded "film" then...but I'd love to see it. I'm just reading about this shit now. I'm thinking it must look a lot like rugby, but with long gaps between tackles.
