The tagline for this 1956 ad from the National Blood Program was “Blood Doesn’t Grow on Trees”. It reminded the reader that her help was needed to replenish the national blood supply.
I found the simple black and white ad to be effective at a time in the mid-century when blood was needed. The Korean War had just ended and polio was a significant threat.
I was curious about the National Blood Program. Was it a government program that still exists? I was not able to find anything in the US called the National Blood Program. After a closer look at the logo, I found that it was a public service project from the advertising council that no longer exists.
It made a good case for why someone should make arrangements to donate blood. The statement is true today.
