I'm not sure what to say about these two advertisements from the olden days. I suppose if one believes the advice of the first ad, the second product was there to keep the consumer fit(?) and trim. (If you're brave, you might need to click the second image to read exactly what's being sold. For the record, I didn't know you could even use the words "sanitized," "jar-packed," and "tapeworm" in the same sentence.)
I'm told these vintage ads are authentic. . . and it makes me shudder. Silly me, to think I was worried about a few bad peanuts and pistachio nuts.
