And here is the original scan I was emailed.
Beautiful Barry Windsor-Smith cover to the first issue of X-O Manowar. Inked by Bob Layton. You can see from the original that the arm and head are pasted on. I wonder what the original pose was. Was he not shooting back? I remember reading an interview with Bob Layton where he talked about the helmet changing quite a few times for this cover.
And here is the printed version.
