As the title says, this is Wonder Woman v1, issues 39-110, running from 1950-1959.
Snipped from Wikipedia: Upon William Moulton Marston's death in 1947, Robert Kanigher took up the writing duties on Wonder Woman. Diana was written as a less feminist character, and began to resemble other traditional American heroines. ... During this time, Diana's abilities expanded. Her earrings provided her the air she needed to breathe in outer space, and she piloted an "invisible plane," (originally a propeller-driven P-40 Warhawk or P-51 Mustang, later upgraded to a jet aircraft). Her tiara was an unbreakable boomerang, and a two-way wrist radio similar to Dick Tracy's was installed in one of her bracelets, allowing her to communicate with Paradise Island.
... Due to a confluence of forces (amongst them the [Comics] Code and the loss of Marston as writer), Wonder Woman no longer spoke out as a strong feminist, began to moon over Steve Trevor, and, as time wore into the Silver Age, also fell for Merman and Birdman.
Wonder Woman experienced other significant changes from the mid-1950s throughout the 1960s. Harry G. Peter was replaced by Ross Andru and Mike Esposito in 1958 (starting with issue #98), and the character was revamped as were other characters in the Silver Age. In Diana's new origin story (issue #105), it is revealed that her powers are gifts from the gods. Receiving the blessing of each deity in her crib, Diana is destined to become "beautiful as Aphrodite, wise as Athena, stronger than Hercules, and swifter than Mercury". Further changes included removing all World War II references from Wonder Woman's origin, changing Hippolyta's hair color to blonde, giving Wonder Woman the ability to glide on air currents, and introducing the rule that Paradise Island would be destroyed if a man ever set foot on it.
