Donald Duck #18/1953

In "Gaat naar de Noordpool [deel 1]", Donald Duck, still fuming over Gladstone Gander’s endless luck, sends him on a reckless quest to Alaska in search of a legendary 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 hiding a Viking ship adorned in gold trim.
