Six-Gun Heroes #16

Smiley Burnette, editor of Burnette's Bugle, faces his most desperate challenge when a mysterious criminal called "Man-Trap" escapes from jail. The story involves rustlers stealing cattle, a secret marshal riding undercover, and a valuable diamond that becomes the object of theft. Rocky Lane pursues the culprits on his fast horse, ultimately confronting Man-Trap in a climactic battle where Rocky knocks the villain unconscious with a boulder and recovers the stolen diamond.
