Walt Disney Comics Digest #21

In "Riding the Pony Express," Donald Duck and his nephews Huey, Dewey, and Louie join a reenactment of the historic Pony Express, eager to deliver fake mail across the rugged terrain. When Donald stumbles upon a crashed plane and takes on the urgent task of delivering real government documents for the stranded pilot, he unwittingly becomes the true courier—unaware that his fellow reenactors are about to ambush him at the pass, believing he’s still playing the game.
