Earthly Chronicles of René Bras du Berry (Ray Bradbury !).

They had arrived on this site in the middle of the desert. To investigate after the disappearance of the first spaceship...

They were mistaken of time thinking to mingle with the human members of a single nation...

Curious for a so advanced technology...

Translation of the drawing:

This is the saucer that breaks the camel's back!

What do you mean? Not the right time, 1943?

No, 1947! Not the right place or the right uniforms!
