Mentzer looked pretty good here . this was when he was training each body part twice per week .
This was his best shape. Massive, full, ripped. This was either from the North American Championships in 77 or a contest called USA vs. The World in 78. He looked great here.
It's a shame that there are so few pictures of these contests, unless you happen to own the magazinez from the 60s, 70's, and early 80's, it's hard to find pictures of many of these shows
