This Space Happy Coloring Book cover from 1953 is amazing. I can just hear Neil's ripping off a caption now, something along the lines of the space woman's kneeling position, the space man's pointing the upright rocket ship.
Beautiful refine artwork style of Floc'h (French illustrator, comic artist and writer). Inspires me to try and work similarly bold illustrative/composition ideas into my work. Note Benoit also very adept at this.
