Exactly What It Says on the Tin
Basically, I'm curious to know if this is something an aspiring writer could do. I've looked it up, and there are a lot of stories and characters that are considered public domain, and not just myths, fables, fairy tales, and classical literature like Zeus, the Pied Piper, Alice Liddel, and Sherlock Holmes.
Apparently, there are a lot of old comic-book characers from the Golden Age of Comics that still fall under public domain, thanks to their creators and publishers not filing for copyright or some such fallacy. Even those being used by Dynamite Press
for their Project Superpowers
series still fall under public domain technically. They've just been interpreted differently by Dynamite for their specific stories. Heroes like Pyroman, the Black Terror, Miss Masque, and the Green Lama, and even villains like the Klaw apparently fall under this category.
So, I wonder, could you write a webcomic about some of these characters, tailoring them to fit your story and setting, without being reprimanded in some way, or worrying about some kind of fallout?
