From Rocklopedia Fakebandica
comic book centered on the "Hepcats," a gang of high school jitterbugs who love swing music. Published by American Comics Group, it lasted seven issues, from 1947 to 1948.
Oddly, when it was reprinted in Australia circa 1957-1959, it was somehow stretched into eleven issues.
The comic is set in Jive Junction, a reference to the 1943 swing film of the same name.
