Thanks to Kirby expert Kris Brownlow for this comment: “This hung in the Kirby house for a time. It is an experimental piece much like ‘The Galactic Head’ where Jack did not use a black ink holding line. It is material like this that makes me wish Jack had tried his hand at painting with oils because I think he would have given us paintings that would have blown the likes of Frazetta out of the water. Jack was a storyteller at heart though, so I don’t think the idea of painting sci-fi book covers in the manner of a Frazetta or Wood appealed to Mr. Kirby at all. Jack didn’t really even like drawing comic book covers, he preferred telling his stories.”
I prefer Jack’s storytelling far more to stand-alone images like the piece above as well, but I must admit if I could’ve gotten Jack to do one commission piece, I would have asked for a kind of extraterrestrial goddess pin-up figure like the figure above. Thanks to Kris for the info and comments.
