Today is the birthday of Jack "King" Kirby.
Most likely, you know him as the co-creator of the Fantastic Four, of which the cigar-smoking Thing was based on Jack.
But, Jack also co-created...
...the Hulk, the X-Men, the Avengers, Captain America, Ant-Man, Groot, Ronan and oh so much more of the Marvel Universe.
Jack Kirby also did work for DC Comics, co-creating the Boy Commandos, the Newsboy Legion, Kobra, the Challengers of the Unknown, creating the OMAC, Kamandi, the Demon, the Forever People, Mr. Miracle, the New Gods (including Darkseid), and working on such books and features like Superman's Pal Jimmy Olsen, Green Arrow, Sandman and so many more.
For all this, hail to the King...Jack Kirby!
