When I saw this ad in one of my comics back in the 70's, I thought the only way to look like Charles Atlas was to do what the guy did in his room (see above, 1st picture in second row).
After trashing my room, I was standing there in my undies, looking at myself in the mirror and trying to see if muscles had somehow appeared on me (see above, 2nd picture in second row)...when my mom walked in on me.
Naturally, she wasn't happy about the condition of my room and I panicked...I said, "Mom, it wasn't me! It was that man's fault!" (pointing at Charles Atlas) as if she would believe that a man in a comic book had come to life and trashed my room. No matter how hard I tried to convince her that it wasn't me, she made me clean and put everything back in their places.
It took me a while to learn what all those words in that ad meant. Subliminal advertising. ;)
