Being born in 64, a few years later, around 69-70, I played with gumby and pokey, slinky, spirograph, etc.
Also, talking about the cold war, we had two or three booklet at home, from the civil protection of the canadian government, that my mom had ordered, and it was showing how to make a nuclear shelter at home, list of items to keep in there, how long you should plan to stay, etc.
I still remembers one of the drawing was showing a car stopped in the middle of the road, with the door still open, and the driver jumping on the ditch on the side of the road, with a nuclear mushroom visible on the horizon.
They were explaining that if you were, say 15 miles away, you still had only a few seconds before the blow from the heat wave hit you, and just by being in the ditch, that could protect you from the wind blast and severe burns. Yep... cold war.... the fear of a nuclear nuke was really present.
My mother let us read those booklets, because they were explaining that parents should explains to their kids what to do, etc. But.. yes, I also had comic books and kids stuff.
