Richie Rich Riches #57

In "Richi Rich and the Missing Money Mystery," the Rich family wakes to find their entire fortune has vanished—literally. When Mr. Rich pulls out his wallet, the cash inside floats up, slips through the air, and disappears, leaving only a mocking voice echoing through the mansion.

In "Richie Rich and the Power of Invisibility," Richie finds himself in a bizarre predicament when an invisible criminal demands ten million dollars a week—or else he’ll kidnap the wealthy kid. Desperate for help, Richie visits Professor Von Blitz, a reclusive inventor on the payroll, only to uncover a startling connection between the crook’s threats and the professor’s latest experiments.
