Something tells me Don Draper was not looped in on this one.
In this TV ad from the 1950s, cosmetics company Dorothy Gray used a little Cold War-era popular science to show hold well their cold cream worked. According to the nice announcer lady, an independent testing lab made dirt that was “just radioactive enough” to register on a Geiger counter, then put it on the model’s face and used a Geiger counter to see how much of the hazardous material their cream washed off versus other brands.
The answer: 2.5 times more! But they neglected to note if that meant their cream got off all the radioactive dirt, or just more of it than other brands did. I hope that model asked for a ton of extra money, because if I were her, I’d be pretty scared that shit was going to give me cancer.
