And in these cases, maybe it would've been just as well!
I envisioned this one being sort of a sci-fi thing, with Ziggy battling the Spiders From Mars!
This one here is the first in a series of covers I did! The backstory is that with the success of the Gorgo and Konga comics (as well as Reptilicus, which had to be changed), Charlton decided to look for a new movie to adapt into a series, and then ending up doing a series of movie adaptations, figuring they'd use whatever sold best for a new series. I also had the concept that they'd sell these to Drive-In Theaters to be sold at the concession stand to help keep the kids entertained until the movie started.
