Mao Tse Tung is quoted as having said "Change will come from the barrel of a gun." Though I don't quite think this is what he meant. Dynamite has had to change the main cover for John Carter: Warlord of Mars #10. The original cover for the issue was going to be done by Bart Sears, but for reasons unknown the publisher has had to change it to this cover by Fritz Casas. They're offering both a color and b&w version just in time for the final order cut-off.
