Issue OneIn a nutshell, confederate Civil War veteran John Carter is introduced, and through a series of misfortunes involving a good friend's run in with Apaches, is pulled to Mars through out of body experience. Once there, he meets different kinds of Martians and becomes embroiled in a conflict between the red and green races of the planet. And, of course, falls in love with a Princess.
This first issue covers his introduction and initial travel to Mars. Many of the panels need reworking, so consider these a kind of detailed thumbnails.
I may rework the beginning even more, focusing on Carter's life before he moved to Arizona. I wouldn't have any problem staying on Earth for two issues if it meant a more solid groundwork for his life and personality.
