I wonder if he had Ross it up this way on purpose.
I think in the 60s one is the Black Beauty that was lost by TWA in early Zep days. He was really upset if you would remember and placed an ad, but it was never found.
The picture on the bottom I have seen before. That has been on fb. The top one is new to me. Thank you for putting it here! Yes I also thought it was 1985. His hair isn't permed like in 1986.
