part two—"The Awesome Vengeance of Grogg" (7 pp). The last page incldes an editorial note that reads: "Want to see MORE of Grogg? Write Stan Lee, Strange Tales, 655 Madison Ave.."
Grogg and Kozlov next appear in issue #87 (August 1961).
Text story with illustration. The first page of this story is printed between the pages of the lead story, while the second page is printed between the two back-up stories. The last page is split with the statement of ownership.
The last two panels were added by a different artist, possibly Sol Brodsky, likely due to a Comics Code problem. The ending is altered so that the demon/devil is a normal man in disguise.
