Superman mod Muhammad Ali

In this landmark 1978 one-shot from Interpresse, the Man of Steel and the Greatest of All Time team up for an interstellar charity boxing match that literally saves the Earth. The oversized comic, written and drawn by a legendary creative team, pits Superman against Muhammad Ali in a bout orchestrated by alien invaders—a high-concept crossover that captures the era's pop culture energy. A unique artifact of its time, it remains a beloved oddity for its sheer audacity and the joyful spectacle of two icons duking it out.
