Donald Duck #20/1953

In "Gaat naar de Noordpool [deel 3]", Donald Duck, still stewing over Gladstone Gander's endless luck, sends him on a reckless quest to Alaska in search of a mythical uranium mine—only to regret his prank when he fears for Gladstone’s safety. With the nephews in tow, Donald tracks him to a frozen wasteland where they stumble upon a mysterious iceberg concealing a Viking ship adorned in gold trim.
