Mighty Comics #49

In "The Deadly Masterminds," the Black Hood and Steel Sterling find themselves united against a threat from the past when time-traveling Dr. Evil unleashes the Monster Master, a long-lost adversary of Steel. With the two villains now allied, their combined schemes push the heroes to their limits in a battle that spans both time and danger. Written by Jerry Siegel and brought to life by Paul Reinman’s dynamic art—penciled and inked on the cover by Reinman, with coloring by Victor Gorelick—this 1967 issue delivers a classic clash of wits and wills.
