Nyoka the Jungle Girl #17

Charlton's fearless jungle heroine faces a genuinely harrowing moment on this cover: Nyoka levels a rifle at a snarling leopard lunging toward her, while two aggressive wild boars close in from below, all set against a dense tangle of jungle foliage. The tension in that standoff — one shot, multiple threats — captures exactly the kind of pulse-quickening drama the "Action Packed Adventures" banner promises. For fans of mid-century adventure comics, this 1948 issue delivers a cover that earns every word of that tagline.
