I've long wondered if Kirby's fine-featured, brooding Hulk was based--facially, anyway--on a certain fine-featured, brooding actor. And yeah, I first posted this on a comic book forum a while back but I'm re-posting it here just 'cause I like these images. So there!

Fun fact: In 1969 Jack Kirby designed the costumes and posters for a production of Julius Caesar at the University of California at Santa Cruz. More info at the Kirby Museum.
