In the 1950s Avon did a number of one-shot comic books...
...based on sci-fi novels.
While most were of tales recently-reprinted by their paperback division, this one was not.
Does a Fate Worse than Death Await Elza?
And...What is Tarrano's Plan?
Based on the novel Tarrano the Conqueror by Ray Cummings, this chapter of the 1951 comic adaptation was penciled by Carmine Infantino and inked by Joe Kubert, the team who would illustrate the first Silver Age Flash story in DC's Showcase #4 several years later!
The writer of the adaptation is unknown.
