Here's a very early photo of (a pre-Superstar) Billy Graham, controlling the action with a grinding side-headlock.  During this formative period in his career, the muscle-bound hippy wrestler teamed with and feuded against some of the greatest names in the business at the time.  From Jerry Graham to Ray Stevens to Pat Patterson, Peter Maivia, Mil Mascaras and on and on, the naturally gifted Superstar became one of the best, in part, because he learned from the best.
