This old ad, from 1963, for Underwood Deviled Ham perpetuates the idea that single women are obsessed with "trapping" a man into marriage:
This 1968 ad from Kentucky Fried Chicken is considered sexist because the headline implied a woman's identity is based on her marital status AND that it's a woman's responsibility to get dinner on the table. I'll give the Colonel props, though, for referring to women as women and not girls — which was the norm in the 60s:
This ca. 1970 ad for Scotch Hair Set Tape literally objectifies this woman by putting her head on a pedestal. What did they do with the rest of her?
That's right, gentlemen, in 1972 men were lead to believe that expensive car tires will help them attract more women. Neither men nor women were ever as stupid as this 1972 ad for Dunlop Formula 70 tires implies:
Yes, we get it. "Sheer enjoyment" and her sheer top. Thanks, 1974 ad for Mannikin cigars, for objectifying this woman. (At least she got to keep her body unlike the hair tape woman above.)
It wasn't enough to put a gratuitous scantily-cad woman into this 1976 ad, Appliance Industries Wheels had her undo her pants:
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.
