C’mon Dummies, Catch those Men
The 1930s to 50s was when most of the selling tactics revolved around women to increase sales. This specific ad shows in a very crisp and straightforward manner what they thought about women and their level of intelligence in actuality.
In their own absurd way, this deodorant ad is trying to comprehend that anyone who is intelligent would know that they should use the product, and the woman in there is a bit dumb to realize it on her own. The catchphrase “Beautiful but dumb” is more than enough to understand what exactly the ad wants to convey.
