The pulp era's legendary superman returns in two super-powered pulp novels by Lester Dent, writing as Kenneth Robeson, that later inspired classic supervillains from the Marvel Age of Comics. First, the Man of Bronze battles "The Metal Master," a criminal genius with the power to manipulate the molecular structure of metals. Then, Doc Savage is sent to prison when he's framed by the murderous teleporter called "The Vanisher." BONUS: Dave Cockrum's 1979 artwork from his proposed Doc Savage newspaper strip. This groundbreaking pulp reprint features the original color covers by Robert G. Harris and Walter Baumhofer, all the original interior illustrations by Paul Orban, and historical commentary by Paty Cockrum and Will Murray.
