Update (via The Raider): This is not the actual cover, but a solicitation - says Jeremy Barlow, Associate Editor at Dark Horse:

 That is NOT the cover to the comic adaptation — it is a “solicitation only” image that Lucasfilm provided for us. The cover(s) will be original painted works by Indy and Star Wars artist Hugh Fleming

Via Diamond Comic’s previews page, we get our first glimpse at the Kingdom of the Crystal Skull’s comic book adaptation, with cover art by Steve Anderson:
