I mean before it got what it is today? I am at work and we have video of Anton "Tony" Hulman at the track in very bad shape (not online, sorry). It peaked my interest in seeing some more.
A few I found online.
Sorta amazing to see what it was like in the 40's and now.
Great pics of the Indianapolis Motor Speedway. It seems like Tony and Wilbur had a lot of work to is a short time to get the 1946 Indy 500 off and running.
