There are a few cartoons that stand out as memorable to me. These I remember though I haven't seen them in years. Some I saw in newspapers, and a couple I saw in the yearly supplements to an encyclopedia. Here are descriptions of a few:
From a 1950s supplement: A kid stands with crutches and watches other kids running and playing as he wonders, "Why didn't my parents get me the Salk vaccine?" (I think it said Salk, but it might have just said polio.)
From a 1950s or maybe 1960s supplement: A personified world, a man whose head is the globe, looks at smallish rocket in the first panel, "The missile." He, a bit unnerved, looks a bigger rocket in the next panel, "The missile to stop the missile." He looks, now worried, at an even larger rocket in the next panel, "The missile to stop the missile to stop the missile." I no longer recall how many panels there were, but in the next to last panel, the personified world has fallen backwards and is sitting, staring up at a huge rocket, "ad infinitum" or such. The last panel has a technician in a lab coat running into a hanger-like building, arms extended, shouting "It's coming back!"
One of the few Peanuts cartoons I remember, from the late 1970s: Charlie Brown panics at it starting to snow, until someone explains that it is just snow. He had thought it was fallout.
From a newspaper in the 1980s: A lone house is labelled "Europe" in the first panel. In the second panel a figure, the USSR, pushes a large nuclear bomb up to one side of the house. In the next panel a USA (Uncle Sam?) figure pushes a similar nuclear bomb up to the other side of the house. In the final panel, a personified Europe is out of the house and yelling "Warmonger!" towards the U.S.
From a newspaper in the 1980s: Uncle Sam is walking away, possibly brushing his hands together, having just hit Libya. Two well-dressed gentleman, representing France and Italy, watch. One says to the other "That Sam, such a ruffian!" Meanwhile both have documents in their pockets, "Secret deals to let terrorists go."
From a campus newspaper, I think: Some scrap haulers are about to remove a junk pile when they're interrupted by a well-dressed fellow, "Stop! That's the Art in Public Places project. The junk heap is over there." And he points to something that doesn't look quite as bad as the alleged art.
On the wall outside a physics professor's office door: A scene of protesters with signs denouncing animal research. The caption reads, "Thanks to animal research, they'll be able to protest an average of 21.4 years longer." I might have the number wrong, but I think I have it close.
