Okay, I feel lucky to have been born in the 90's, because if I was a child during the publishing and teachings of this safety manual, I would probably be damaged for life. Whoever created this had a very direct way of communicating, I'm sure. Check these kinda funny, but mostly "wtf?" scenes from the 1950's kids safety manual, just don't show them to your kids!
You Will Never Sleep After These 1950's Kids Safety Manual Scenes!
Although badly drawn, and creepily direct, I give the manual props for effect! I would never go outside after looking at it.
