So I've come across a lot of Jack Kirby related goodness over the past few days and wanted to share. First up, an amazing blog with tons of high resolution Kirby scans, art and insight into the work he created. Check it out here - Kirby Dynamics. And then there are a a couple of videos of Jack Kirby, one an interview on Entertainment Tonight and another of him drawing Dr. Doom in his home studio in 1983.
Oh, and one more link detailing Kirby's obsession and eventual use of The Ancient Astronaut Theory in his work.
