Upon further research, the question was raised: Was Jack Kirby an uncredited contributor to the greatest Astronaut Theology epic of all time? Or was he- again- tapped into a vision of the future that he projected onto the page?
Remember there was no Stargate sequence of this type in the original story, The Sentinel. Arthur C. Clarke and Stanley Kubrick were still struggling over the 2001 script at the time this comic hit the stands- did they happen upon this story while working on the Stargate sequence, or is this an amazing Synchronicity?
The journey ends in Wizard of Oz-like fashion when the astronauts visualize themselves back on the Moon.
Read this remarkable story in its entirety here.
Later Kirby would do his own version of 2001 for Marvel, but probably had no memory of "The Great Moon Mystery" and its own "Stargate sequence" while watching Kubrick's film.
But damn, that man was tuned in, like few before or after....
