Overseen by Joe Simon, all the titles featured work by many well-known creators, including Jack Kirby, Bob Powell, Wally Wood, Otto Binder, and the earliest known work by Jim Steranko.
In the mid-1960s, with the camp craze created by the Batman television series, Harvey approached Joe Simon again to oversee a new line of comics, mainly superheroes, but with science fiction/fantasy stories thrown in as well.
They also continued the Thrill Adventures title Warfront, after a 7-year hiatus.
The line was unsuccessful, and all of the titles ended abruptly with the March 1967 issues.
House ads showed the covers for Jigsaw #3 and Thrill-O-Rama #3, but those issues were never published.
