Jack Kirby created Julius Caesar Costume Designs for a College - 1969
Proving what you know is true. It never hurts to ask!
This production of Julius Caesar got the idea to contact Marvel comics to ask for help. And what they got was probably over and beyond what they were looking for.Via - The Kirby Museum: "In 1969, Sheldon Feldner contacted Marvel Comics, asking if one of Marvel’s artists would be interested in designing costumes for a production of William Shakespeare’s play Julius Caesar by the University Theatre Company at Santa Cruz at the newly-built Cowell College of the University of California at Santa Cruz.
As luck would have it, the Kirby family had recently moved to California, and Stan Lee recommended that Feldner contact Jack Kirby. Kirby designed the costumes and provided a drawing that was used on posters, handbills and programs at no cost to the students."
Here are a few costume test shots.
Later on a lot of these costumes were used in the comic series The New Gods for DC Comics in 1971. Which launched the land of Apokolips, a nightmarish, ruined dystopia filled with machinery and fire pits and is ruled by the tyrant Darkseid.
The collected version of The New Gods is available on Amazon.
