Okay, so why wasn't Kane's cover used, though you can see the title changed, and actually Neal Adam's cover is better because the angle of the comet earth is more acute, aiming right for our intrepid moon men, and the angle of the scene puts them in more imminent danger. Was Kane's rejected? But why not have him redraw it? A whole bunch of other meaningless questions come to mind, but all I know is—any answers might stagger the imagination and would come from . . . BEYOND the UNKNOWN!
