In 1966 Esquire magazine ran a piece on the rise of comic books in campus culture. Through Marvel, they got Jack Kirby to illustrate the article and do a cover for the issue. Tragically, the cover was not only never used, it was lost and has remained unprinted to this day, and has only ever been seen by a very lucky few. So, no cover image for this post. I'm going with the lost Kirby cover.
Here's full page view so you can see how it all went together, even if you can't really read much in these images:
