So far, I have run across four ads for Kruschen Salts, and the people in them all look really creepy.
The first one is from the August 21 1923 Toronto Daily Star:
That old guy in the water looks happy, but he looks a bit strange, as if he is on uppers or something. But he’s normal-looking when compared to the older guy in ad in the September 27 1927 Toronto Daily Star:
The young man is in despair because he wants the creepy old guy to go away. In this ad, I notice that the sole importer of Kruschen Salts has changed. Perhaps they just found a Toronto distributor as well as a Montreal one.
Next, we have an ad from the November 21 1932 Toronto Daily Star:
This “wonderfully active” 66-year-old woman (Mrs. E. W.) looks a bit more normal, except for those eyes: once again, she looks like she’s high on amphetamines or something. It’s deeply disturbing.
The last one is from the March 31, 1931 edition of the Toronto Daily Star, and I think it’s the creepiest one of all:
Oh my God, the zombies are attacking! Run before it’s too late!
I couldn’t find out much about Kruschen Salts, other than it has been around for a while. A British site mentions that it first went on sale in 1922. One of the ads here claims that Kruschen Salts contains six salts, but the drugs.com website lists only sodium chloride as its current active ingredient.
