The first is Heroes-Inc, written and illustrated by Scott Austin. His story gives us an interesting modern updating of the characters that seems to retain the spirit of the characters very well. Check out this nice bit of teaser text:
In a world where the Allies of WWII lost the war and superheroes are believed to be nothing more than pulp fiction, the world is shocked by alarming reports of super villains emerging around the globe to terrorize and wreak havoc.
Archibald Masters, The American Crusader, now an old man, sets out on a mission to find the remaining Golden Age heroes and take DNA samples from them in order to create a new generation of heroes to serve and protect the country that is so dear to his heart.
The other one to check out is Out of Print, produced by Michael Parkinson. OOP is a parody web comic that uses a lot of familiar Public Domain Heroes in some pretty funny situations.
Out of Print uses characters from the golden age of comic books that are now in the public domain. In fact the strip itself is set around a support group for superheroes that find themselves in that very situation.
Here is a perfect example:
Dear Flashback Universe you should remove your comics if you don't want to be sued by IDW they are the only ones who are to be printing Black Terror and you will be sued by them if you do not take your comics downs. - Andros.
Why do people feel the need to try and convince me that I'm going to burn in Copyright-Hell because I've posted a public domain issue of the GA Daredevil? Are they Alex Ross fans gone bad or something? Do they think I'm somehow depriving Alex Ross or IDW or whoever of some necessary source of income? I have to ask because they rarely want to reply when I explain how Public Domain works.
Anyway, enough of that... have a great day!
