How many leches — and gullible boys — sent away for these X-ray specs? Must have been a lot because I remember seeing this ad in the back of magazines and comic books for years and years.
"Take off all your clothes, doll. It's okay, I'm an artist."
This vintage ad is from before my time. It promises to teach you hypnotism and how to "bend people to your will, banish fear, worry and opposition." I think the men who sent away for this had on their mind something other than making young women cluck like a chicken.
This ad promises to teach you how to hypnotize a person without her knowing about it. Pretty sure that was already illegal when this ad ran.
