Guardians of the Galaxy #13

Set in Marvel's 31st century, this 1991 installment of Guardians of the Galaxy poses a thrilling question right on the cover: "Is This the Ghost Rider of the Future?" A flaming-skulled figure astride a futuristic motorcycle blazes through the cosmos, while a blue-suited Guardian scrambles on a planetary surface below, caught in the path of that supernatural hellfire. Jim Valentino and Steve Montano deliver a cover that crackles with cosmic energy, blending the spirit of vengeance mythology with the far-flung sci-fi setting that makes this series such a distinctive corner of the Marvel Universe.
