These old magazine ads were sent to me about four years ago by one of this blog’s most active visitors, Mark Winchester.
I don’t see a date on them but there are a couple of clues.
– The ad copy refers it astronauts so I’m guessing it’s in the era of the Mercury program which ran from 1959 to 1963.
– The mailing address for the company in New York does not have a ZIP code. That system started in 1963. While individuals might not have adopted ZIP codes immediately, it’s likely a mail order company would have.
So I’d say 1960-62 would be an educated guess.
That’s nearly 60 years ago. And the ad copy references research done in Germany in the 1920’s which is knocking on 100 years ago.
And no doubt, some Neanderthal 50,000 years ago tried for years to roll an inconvenient boulder away from his cave without budging it an inch while getting progressively stronger every year. But that’s just a wild guess on my part. He might not have been Neanderthal. Hehe.
