Moebius, real name Jean Giraud, passed away earlier today after a battle with cancer. He was 73. Moebius is best known as a comic book artist, mainly doing one-off illustrations but he did apply his talents to Silver Surfer: Parable, The Halo Graphic Novel and creating Blueberry, an atypical cowboy.
