Full picture. Sergio winning the 1967 Mr. Universe championship.
Maybe he's standing closer to the camera but the fella to the right looks like a giant compared to the other two.
There is something odd about his back. His lats appear to begin very high and the section below them is a straight as a box.
It's Claude Groulx, I think it is nerve damage like Wolf has now. The lower back will simply NEVER fill in.
