Giant-Size Marvel Adventures The Avengers #1

In "The Coming of Namora!", the lone survivor of a brutal attack on her undersea home seeks justice with the help of her cousin Namor. After fleeing the wreckage of her people’s destruction, Namora joins Namor in tracking down the ruthless "Stoop" Richards and his gang, leading to tense confrontations aboard a gambling ship and a remote island. The story, illustrated with dynamic energy by Ken Bald and George Klein, introduces Namora to a new world—and a new ally—in the form of Betty Dean. Cover by Leonard Kirk and Terry Pallot captures the moment of Namora’s arrival with striking detail.
