Those are cool pieces of history.

I wish I had a scanner, because I have an ad from a 1970 magazine featuring a citrus green 70 Z/28 identical to mine that shows an 18-24 year old guy admiring the car while his blonde girl in a plaid mini dress stands there patiently waiting for him.
The headline reads "Seperates the men from the toys". LOL, you'd be hard pressed to get away with that ad today.
