The third, and final, issue of Captain Zero (March, 1950), cover by Raphael DeSoto.
Captain Zero was a relatively obscure pulp title, showing up as the pulps were dying, killed off by comic books, paperback books, and the emergence of television. It was also the last crime fighter pulp magazine.
Captain Zero was, in everyday life, a guy named Lee Allyn. After exposure to radiation he became invisible every night at the stroke of midnight, and stayed that way until dawn (I don't know if this ability was affected by Daylight Savings Time).
Of course, Allyn decided to use this new ability to become a vigilante and fight crime. He had one Achille's heel, though: his eyes remained visible at night.
Captain Zero was published by Popular Publications, one of the largest pulp magazine publishers in the country. Among the many titles it produced were The Spider, G-8 and His Battle Aces, and Operator No. 5.
