Wonder Woman #89

In "The Master of Earth's Twin World!", Wonder Woman faces a bizarre threat from alien invaders testing humanity’s strength—unaware that their greatest challenge is already among them, as Diana Prince and her Amazonian identity are one and the same. Written by Charles Moulton and illustrated with bold precision by Harry Peter, this 1957 classic blends sci-fi intrigue with the enduring mystery of Wonder Woman’s dual life, all brought to life on a striking cover by Irv Novick and Mike Esposito.
