Donald Duck #21/1953

In "Gaat naar de Noordpool [deel 4]", Donald Duck, still stewing over Gladstone Gander's endless luck, sends him on a reckless expedition to Alaska in search of a fabled uranium mine—only to panic when he realizes the danger Gladstone might be in. Rushing to his aid, Donald and the nephews follow the trail to a frozen wasteland, where they stumble upon a mysterious iceberg hiding a long-lost Viking ship, its gilded hull glinting beneath the Arctic ice.
