Walt Disney Uncle Scrooge #138

In "The Many Faces of Magica de Spell," Magica de Spell concocts a bizarre potion that makes anyone’s face mimic the last face they looked at. When Scrooge McDuck learns of it, he flees Duckburg with his Old Number One Dime, seeking refuge in a remote jungle valley inhabited by a mysterious race of faceless people. Magica tracks him down and sprays the potion on his face, setting off a chain of unsettling transformations.
