When I saw this cover in the late 70’s, I knew that Luthor and Brainiac couldn’t really kill Superman. But I had to buy this comic and see what was going on. Imagine my surprise when I saw that the villains really do kill Superman! I won’t give away the ending except to say it involves a tribe of immortal aliens living in the bowels of the earth who secretly worship Superman. And Brainiac betrays Luthor … of course.
