Jack Kirby is called 'The King of Comics' for a reason, during his career that spanned six decades he gave us many of most iconic characters the medium would ever see. From his introduction of Captain America at the height of World War II it was clear he wasn't your ordinary comics artist. But it was his creative explosion at Marvel Comics in the 1960's that cemented his legacy, over a short period of time Kirby would give us The Fantastic Four, Iron Man, The Hulk, The X-Men, Thor, Ant-Man and Nick Fury just to name a few. Kirby would then go to DC and create his Fourth World, introducing Darkseid, Mister Miracle, The New Gods and a host of cosmic supporting players. Long live The King.
Swan was a house artist at DC working on titles like Tommy Tomorrow, he began gravitating towards Superman and his related books, Superboy, World's Finest and Jimmy Olsen, he would eventually leave DC thanks to his personality issue with Editor In Chief Mort Weisinger. He would eventually return and go on to be the artist that defined the look of Superman in the Silver Age, eventually becoming the editor of the title, but after thirty years of keeping up standards of all things Superman, Swan was given the boot in favor of John Byrne's Superman reboot, Swan's comic work began to taper off after this dismissal and he eventually retired, but will forever be recognized as the Silver Age Superman's finest artist.
