I've been on an old pulp kick lately and I'm looking to do some writing featuring some of my favorite pulp characters, but since most of my favorites are not in the public domain, I will need to find some similar characters to work with instead.
I know there are plenty of Tarzan clones in the realm of golden age comic characters, can someone please recommend one that is pretty decent, and in the public domain too?
I am also looking for public domain comic book characters that would work as good substitutes for Doc Savage and John Carter. Any help would be greatly appreciated...
