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).
