DC Comics has released a new set of covers for its "Earth One" original graphic novel line. Posted by Nerdist, the images include the finished cover for J. Michael Straczynski's "Superman: Earth One Volume Three" by Ardian Syaf and Gary Frank's cover for "Batman: Earth One Volume Two" written by Geoff Johns.

The previous volumes of both "Batman: Earth One" and "Superman: Earth One" released in 2012, and two years have passed since any new "Earth One" graphic novel was released. However, DC co-publisher Dan DiDio stated in March that the publisher plans to recommit to its line of original graphic novels.

"I think it's very important, because it allows us to tell stories with our primary characters at a different style and pace than we normally do in the periodicals," DiDio said. "[The creative teams are] going in with that knowledge, so they're able to pace themselves properly, and understand that this is what their primary focus is going to be. We find them other work in between -- you might get a cover or two here and there. Even when we were working with Gary Frank, he was able to squeeze in some 'Shazam' material in between the 'Batman: Earth One' books. We always find ways to keep them out there and available, but on the other side of the coin, we really want their focus to make this the best possible project for them."
