I thought that I had read every english speaking Christian comic book in the world. However, Christian Comics Clearinghouse has proven me wrong. You can check them out at http://www.christiancomicsclearinghouse.com/ or by clicking on the title above. They tell you how you can contact the publishers and buy from them. They have started the ministry in their local area to put Christian comic books into their local bookstores.
