Superman Presents Wonder Comic Monthly #31

In the imaginative tale "The New Superman and Batman Team!", Kal-El’s powers are stripped by gold Kryptonite during his journey to Earth, setting off a chain of unlikely transformations. Lex Luthor, wielding a mysterious serum, gains superpowers and takes on the mantle of Superboy—then Superman—while Clark Kent, driven by grief, becomes Batman to avenge his foster father’s death. Written by Cary Bates and brought to life with Curt Swan’s iconic art and George Klein’s inks, this 1967 adventure reimagines the duo in bold new roles, with Swan and Klein also responsible for the striking cover.
