It's easy to criticize Franco 40 years later but back in the early seventies he truly was a freak
in his own unique way. Nobody to this day has that kind of chest. That prominent upper split.
When I first saw him in PI it was jaw dropping. Everyone had their own unique look during that era. 
Now they all sort of blend together. 
I always thought Franco was a better bber than Zane during their prime.
