Christopher Moeller is an illustrator and comics artist who is one of the foremost proponents of fully-painted comics art. Rather than the traditional um… lines and colors format, each panel is a painted image. Many painted-comics artists use watercolor (see my post about Alex Ross), but Moeller uses an opaque medium (it looks like acrylic or possibly gouache). There are only a handful of artists who can really make this work and Moeller is superb at it.
Moeller has done a number of painted comics stories, numerous comic book covers as well as illustrations for games, gaming cards and posters. There is checklist of his work (from 1991-2003) on the site. There are also prints and original art available.
In the late 90’s he illustrated (and wrote, or co-wrote with Kevin Moeller) an extended painted-comics science fiction series that builds on his interest in military history to create a rich setting for stories of interstellar conflict and intrigue. The stories have been collected in two graphic novels: Iron Empires Volume 1: Faith Conquers and Iron Empires Volume 2: Sheva’s War. There is a site devoted to the series, but it’s still incomplete. There is a preview of Volume 1 and Volume 2 on the Dark Horse Comics site.
DC comics has just released Book One of a two-issue superhero/sci-fi series, written and painted by Moeller: JLA Classified: Cold Steel.
