"Whatever your attitude toward use of the atomic bomb, you must live with the fact that it exists," commands this ad. About the self-protection steps it details, "The wise citizen of this atomic era will memorize them so thoroughly that their use would be almost instinctive."
So, I'll need to look into this further, but did Mutual of Omaha offer "surprise atomic attack" coverage at the time? The ad doesn't make that clear.
