This week, the honor of the Worst Cover Ever distinction goes to Action Comics #469 (1977). Here we find Superman enduring the most humiliating experience of his long history as Terra Man, a villainous space cowboy (yes, a space cowboy) attempts to "break" the Bronco of Steel.
I can't decide which is more disturbing: the wince-inducing visual or Terra Man's "doggone, if you ain't the most rambunctious bronc I ever rode" line. I know images like this aren't supposed to alarm us in this sensitive, post Brokeback Mountain world, but doggone if that ain't messed up somethin' fierce! WA-HOO!
