Ditko somehow managed to do original THUNDER Agents work for four different publishers over the years. First of course for the original Tower series with Wallace Wood. This one was for JC Comics, on a series reprinting some of the original 1960s Tower stories. No Ditko reprints in this particular issue, but he pencilled the NoMan cover, with inks by Willie Blyberg. The same image, with slightly different colouring, appeared on the backcover of the issue without logos and such.
Ditko would later do a new NoMan story intended for JC Comics' original THUNDER AGENTS book, but wound up in an Archie comic instead. Then he'd also do a couple of stories for Deluxe's WALLY WOOD'S THUNDER AGENTS.
