a) My idea here is that Giger understood that the painting in the Apollo Astronauts poster by Pierre Mion, that would be published as supplement to National Geographic Vol. 144, No. 3 (September 1973) referenced Salvador Dali's painting "Uranium and Atomica Melancholica Idyll" (which appears to have a different arrangement of the words in its name every time I see it written somewhere. I can't remember the actual name) and so he compared the shapes along with the photograph of Louis Jourdan as Dracula
|"Apollo Astronauts" (Published as supplement to National Geographic Vol. 144, No. 3 (September 1973)) by Pierre Mion.
b) Left half of the Eagle lander becomes a curious insect like creature. The landing leg becomes the arm of the creature.
c) The side thrusters chamber becomes an eye
d) The helmet becomes a lower bottle shaped bulbous form while the astronaut becomes a slightly taller bulbous form. The side flap of the astronaut's helmet becomes a diagonal tongue like limb extending from the smaller shape to the taller of the bottle like shapes in Giger's painting. A crater pot becomes a leg like form. The comparisons here are broken down further below
e) The helmet with side flap becomes a bottle shape with a tongue like form sticking out. The shoulder of an astronaut behind becomes the nozzle of the bottle.
f) The astronaut head and shoulders becomes this bottle like creature to the right of the one mentioned above, with the collar of the astronaut becoming the collar of this strange creature. The astronaut in the distance becomes the nozzle of the bottle like form.
g) Ground before a crater pit and the shadowy ground within are turned into a leg like form.
