In Joel Frieman's imtroduction, he details how Stan Lee stated he was inspired by the 1930s pulp hero, The Spider, when he co-created Spider-Man. But you have to see this, too--here just may be the first appearance of Iron Man, in "Satan's Murder Machines," and very specifically called "the IRON MAN!" Here's that 1939 pulp, complete with interior art by John Fleming Gould.
Plus a brand new painted cover by the legendary Ken Kelly, protégé of Frank Frazetta himself. Then flip the book over and you get a second story, based on a Norvell Page work, newly written by Frieman and illustrated by Kelly: "Smilodon Versus the Council of Evil." It's justice with a smile, also starring both the original Spider and Iron Man.
