1967 sortof aerial:
I'm sure there's a bigger version but as i don't have a gettyimages account.
If you want good historical detail then ask around at srmz.net and places too, they are usually quite helpful for historical stuff.
It would be cool if you'd base it on a version before 1970 rather than 1970 itself. Basically a version before they armcoed the entire circuit (rather than just specific corners) would be a lot more atmospheric and interesting.
Does anyone have a trackside pictures of the loop from those times? The gpl version dips a breathtaking amount compared to modern versions of the track. I am wondering whether this is just due to it being innaccurate or whether they levelled it slightly over the years in view of safety. Maybe it is a bit of both.
Certainly my early impressions of gpl and dying spectacularly dropping down into the loop with way too much speed off into the haybales and over the fence are special memories haha.
