The old claim that one can see many of the Wonders of the World from space, like the Pyramids. and the Great Wall of China.
The story about the Great Wall of China being visible from space came from a story in a comic which I read here in New Zealand, probably as a teenager in the early 1960s.
I don't recall who the characters in the story were or even which comic exactly, but I vaguely recall that the pictures were black-and-white line-drawings and that it may have been one of the many stories in one of the 100-page comics that were popular at the time.
The story went something like this: Some bad aliens set up a problem for the Earthling spaceman-hero by producing a duplicate Earth close to the real one, and somehow they forced our man to use a weapon to blow up one of the Earths with a 50/50 chance that he might pick the wrong planet. The two Earths were shown as large globes, so probably not from as far away as the moon. Luckily for us, he blew up the one that we weren't on, and how he managed that was that the aliens hadn't included the Great Wall of China on their duplicate Earth so, although he was out in space, he could see which was the fake and which was the real one.
I wonder if comic nuts could find that story now-days. It would be great to show the origin of the modern myth.
