Did you catch the product name? It's there in the red callouts: Kelp-a-Malt. With a name like that, it's got to be ... extinct.
Une Femme doesn't reveal the source of the ad, but it's easy enough to find: just Google Kelp-a-Malt. My search ended at the Modern Mechanix blog ("Yesterday's Tomorrow Today"), where I learned that the ad appeared in a 1934 issue of Physical Culture magazine.
What an artifact. Remember when people wanted to "add 5 lbs. of solid flesh in 1 week" instead of being The Biggest Loser? Neither do I. But indeed, there have been times and places when people obsessed about being too skinny. The Great Depression, when money and jobs were scarce and thinness often signified poverty (rather than wealth, as it does now), was one of those times, and the United States was one of those places.
But that's just the beginning. There's a lot of text under the ad's headline, including this:
Mmmmmm: FOOD IODINE.¹
And the kicker:
Kelp-a-Malt. It's descriptive, it's derisory, it's disgusting. Doesn't it sound like something you'd whip up in the Super Bass-o-Matic? And like nothing you'd want to consume? Oh, how I wish I could have been at the creative session that produced that name. "How about Seaweedies?" "No, Blubber Up!" "Wait a minute, gentlemen, it's right here in the ingredients! Kelp. A. Malt. Kelp-a-Malt!"
Rest assured, I will remember the name. In fact, right now I'm sort of wishing I could forget it.
¹ By the way, according to commenter #31, Kelp-a-Malt was eventually withdrawn from sale because of false nutritional claims.
