Yesterday was his birthday. He would've been 90 years old.
There's a kickass cover gallery of some of The King's work over at Marvel.com that is worth checking out. My personal favorites are his renditions of Thor and the early X-men. Kirby's style is both iconic and energetic, being an inspiration to all those that followed in his footsteps. Looking over all this, I'm reminded of a time when Photoshop didn't exist. When filters and glares were irrelevant. It was an era when pencil met paper, and a vision was created. The King did it so easily, so earnestly, and that's what is most admirable of his work.
