I ran across another Jack Kirby cover image on the Internet with a Frankenstein theme. The cover is from the 1970's DC comic book The Forever People # 9. I'm a bit surprised, but happy, at the number of times Kirby seemed to go to this gothic theme in his work during the 70's.
Jack Kirby and Stan Lee's Doctor Doom, in Marvel Comic's Fantastic Four books, is an example of a Kirby gothic theme from the 1960's. Whenever the plot line of the books took the Fantastic Four into Latveria, Doom's kingdom, the images were full of villagers with torches and stone castles - plus a healthy dose of Kirby's futuristic weaponry.
