In the Sandman’s first appearance, Spider-Man sucked him up into a giant vacuum cleaner to ensure victory. Since then, his career really hasn’t improved much. But no matter how big of a loser Flint Marko might be, he always makes for some rather impressive visuals. And in this classic cover, designed by Jack Kirby, the Sandman looks as imposing as ever, complete with green gimp mask and a menacing grin.

Kibry’s name gets brought up ad-nauseum when it comes to the greatest comic book artists; when you can make sand look dynamic, though, you're simply better than the rest.
