I remember seeing a photo–maybe in Time Magazine–of an NFL player with a little bit of hair sticking out of the back of his helmet. The photo showed him from behind; you didn’t see his face. I don’t remember if you could see his uniform number, name, or team.
At the time, all athletes had short hair and this photo was saying, in an amusing way, “Look, the hippies are getting into sports now.” I have tried searching for this but have not found search terms that narrow it down enough. I am hoping someone else will remember this photo, and maybe remember the source so I can find it.
(Because this is a factual question about a specific photo, and not the sport or the artistic aspects, I put in here rather than Game Room or Cafe Society.)
