Donald Duck & Co #9/1968

In "Skjebne-diamanter," Scrooge McDuck sets out with $10 million in gold to secure the world’s largest diamond in Southern Miserystan, traveling in a ship designed to foil even the most cunning pirates. When the Beagle Boys launch a daring attack, Scrooge holds his ground—only to find that victory brings more than just treasure, as a strange streak of bad luck soon follows him, and then, unexpectedly, the Beagles.
