Superman et Batman et Robin #18

In "La fin du chef," Lex Luthor teams up with the Legion of Super-Villains from the 30th century, unleashing a threat that forces an adult Legion of Super-Heroes to travel back to the 20th century to intervene. Written by Jerry Siegel and brought to life by Curt Swan’s dynamic art with Sheldon Moldoff’s inks, this 1970 issue delivers a high-stakes clash of eras, where heroes and villains from different times collide.
