Walt Disney's Donald Duck Vol. 7: Lost in the Andes
This volume begins when Barks had reached his peak ― 1948-1950. Highlights include the title story, “Lost in the Andes” (Barks’s own favorite). Donald and the nephews embark on an expedition to Peru to find where square eggs come from only to meet danger in a mysterious valley whose inhabitants all speak with a southern drawl, and where Huey, Dewey, and Louie save Unca’ Donald’s life by learning how to blow square bubbles!
