User blog comment:Chugite/so are Quality Comics characters public domain or what?/@comment-1212133-20101120055938/@comment-1432399-20110201190855

Actually, many (but not all) of the Blackhawk comics from the 50's HAD their copyrights renewed, either by DC or "Busy" Arnild, but as far as I know none of the Military/Modern comics were. I found this list of characters that DC hasn't yet used in any of their comics, all of which SHOULD be PD and free of trademarks, on Wikipedia: 711, Ace of Space, Blue Tracer, Destiny, Destroying Demon, The Dragon, G-2, Ghost of Flanders, Just 'N Right, Margo the Magician, The Marksman, Monsieur X, The Mouthpiece, The Raven, the team of Red, White, and Blue, Rusty Ryan, Scarlet Seal, The Sniper, Spider Widow, The Unknown, USA, The Voice, The Whistler, Wildfire, Wonder Boy and Yankee Eagle.
