From its inception The New Yorker has carried weekly advertisements for Fleischmann's Yeast, which apparently cures everything from acne to insomnia, meanwhile improving "digestion" and upping the energy levels of people who had all but given up hope.
The ads always have photographs of healthy, vigorous people demonstrating what they can now do thanks to Yeast. All of them were in some way notable before their digestive/acne/blood problems began, and all of them are now able to return to the strenuous activities with made them notable in the first place: dancing, golfing, fishing.
Here's a sample testimony for Miss Myrtle R. Ivins from Philadelphia, pictured above:
During business hours, I meet many people, including the officers of the large firm where I work. Naturally, my embarassment was almost unbearable when, after an illness that upset my blood, my face broke out in pimples. I was actually ashamed to meet anyone.
What made it hardest to bear was that formerly my skin had been especially clear--kept so by an active outdoor life. I played some tennis and golf, swam and rode a little, and had done my share of hiking. But I had to give up all these sports, I was so badly run down. My whole digestive system became unbalanced.
My doctor suggested Fleischmann's Yeast. Today, after eating it faithfully every day for over six months I feel fine. My face has improved greatly. My appetite is splendid. I'm able to be back in the open once more, enjoying the sports I love.
By the 1940s these "yeast miracles" became fodder for radio comedians; I've heard many radio spoofs of the time that feature over-the-top testimonials about the life-changing effects of yeast.
