Fake flag on the moon. This is here say, but came from the artists niece. She did not think it odd her uncle could know what the moon would look like before we ever got there.
Here is an interesting curios second hand account.
I met a woman three years ago. She mentioned her uncle was an artist and actually did the artwork for many many sci fi novels. She then said he was approached by NASA to paint what it might look like if we were to go to the moon.
The whole family remembers this painting of astronauts on the moon with the flag. Many years later the the moon landing occurred and there were astronauts photographed on the moon in the exact position as the uncle had once painted.
The only difference was the waving/not waving flag. That changed because the atmosphere was not as the uncle had thought.
The sci fi book covers were mostly large faces and tiny people walking into the mouth on colorful wicked looking terrain.
Another day, this woman told me her mother wanted uncle to paint a portrait of the woman as a child.
He painted her with a different color dress and a darkened, featureless face. Head to toe, creepy.
I suspect he was a mason and got these opportunities from other masons. I struggle to remember his name, but l have looked him up.
