"He gave me a list of the twelve characters and away I went; it's actually the fastest gig I've ever done. I painted all twelve covers in just ten days, so it's been a fantastic cover gig for me to do. I sat down and did all the sketches in one day while I was still in my first inspiration for the job, and then I just painted them one by one." - THE MARVEL ART OF MARKO DJURDJEVIC
JOURNEY INTO MYSTERY #104 came out in early 1964 which was before I was reading THOR.
When Marvel released their first set of cards and stickers in 1967 I first saw the iconic Christlike pose. Even though I knew that Marko's exposure to comics was limited to a few years in the mid 1990s and then not again until he was hired by Marvel it occurred to me that he might have seen the Kirby image.
It is easy to say this now that I know the truth but my best-faith guess would have been that Djurdjevic was not influenced by the Kirby cover.
Hagen, Marko's assistant, posed my theory to Marko and he supplied a definitive answer: "I've asked Marko about the Kirby parallels, and he said that it is not the case. He says he's too young to be grown up with Kirby's work. Later he didn't get a connection to him, as he was confronted with other artists that inspired him more (like Enki Bilal, Tim Bradstreet, Phil Hale and Joshua Gabriel Timbrook, an almost unknown illustrator)."
