Chesley Bonestell's "Stone Architecture on Mars, Demonstrating Mars' Two-Thirds Less Gravity Than Earths." (Exploring the astronaut figures)

a) Perhaps Ralph McQuarrie thought that in the Bonestell painting that there were aliens crouching between the pillar and so used the idea in his Cantine painting. 

Chesley Bonestell's "Stone Architecture on Mars, Demonstrating Mars' Two-Thirds Less Gravity Than Earths."
