Here’s a propaganda cartoon from 1956, put out to benefit the American petroleum industry. I’m at a loss as to who this was meant to be shown to… school kids, perhaps? In any event, it uses reasonably good (for the time) animation to extol the virtues not only of petroleum, but of the competitive capitalist economic model. In other words… pretty much exactly what you would not expect to see today.
It’s interesting to see what American society put out to promote itself when the US was in undeniable ascendancy, compared to the self-flagellating barf that tends to get promoted now that the US is seemingly in self-imposed decline.
