NoMan, a cloaked hero with the power of invisibility, was a member of T.H.U.N.D.E.R. Agents, a team of superheroes first published in 1965 by Tower Comics. I didn’t read them until 1976, when I bought a black and white reprint comic, Uncanny Tales, when I was in Stirling. I don’t know whether any of the other agents time traveled, but NoMan did in both of the issues of his own comic (in Nov 1966 and Mar 1967).
Trapped in the Past!
