I’ve got one on my office wall ‘How and What to Tell a Communist’ from Timken Roller Bearings.
"The Grasshopper and the Twig"
To the bulging eyes of the grasshopper it was just a spray of green young twigs, full of sap and spring.
The next instant one of the twigs lunged forward. The 'hopper was clamped in a pair of vise-like arms. The Praying Mantis, twig-shaped hunter of the insect world, began to dine.
Natural comouflage is not restricted to insects. Human "twigs", too, disguise their dedliness. Communists look and act and talk just like other people.
If we as individuals cannot penetrate the Communists' disguise, how can we possibly combat them?
The answer is so simple it is widely ignored. We can keep them out of positions of trust, where they can really harm us--simply by being in those positions of trust ourselves.
It means that many more of us must make the same kind of extra effort the Communists willingly make. It means ordinary citizens getting into active politics, joining civic organizations, doing the jobs the Communists would like to do.
It means work, no two ways about it. But if true Americans don't do it, Communists gladly will.
And it's work by which we could provide a powerful defense against our perfectly-disguised enemies, the Communists.

Well, we sure can't say that nobody saw this coming. The above is from 1963, I believe.
