Li'l Genius #15

This Charlton charmer from 1957 finds Li'l Genius in full mischief mode — cover artist Frank Johnson captures the red-haired scamp mid-whistle, slingshot in hand, as a dramatic "CRASH!" cloud of scattered bones erupts next to a museum-style "Dinosaur" sign. A disapproving little face peers down from the corner, and the whole breezy scene promises exactly the kind of good-natured trouble that made this series such a delight at a dime a copy.
