Action Comics #274

In "The Reversed Super-Powers!", Supergirl takes on a history assignment by journeying to the past to witness legendary figures like Annie Oakley, Betsy Ross, and Pocahontas firsthand—only to find her powers mysteriously reversed in each era, all while evading the ever-present threat of kryptonite. Written by Jerry Siegel and brought to life with dynamic art by Jim Mooney, this 1961 adventure blends time-travel intrigue with classic Superman lore, all capped off by Curt Swan’s iconic cover and Stan Kaye’s sharp inks.
