Anyone recognize this Earthrise poster because I have never seen one like this? Vintage 60s or not? Color bars may indicate date?

Saw poster like this hanging up in the science classroom in the high school in early 1970s.

When I was in publishing, our colored printed material often had the color bars seen in the photo. They were trimmed off of the final product.
They represent the four colors used in four-color printing: black, magenta (red), cyan (blue) and yellow. They’re the same as the colored inks one purchases today for color ink jet printers. It’s probably related to that rather than the date.
