In 1943, Clue Comics featured a two-issue arc about the Boy King of Swisslakia, his friendly giant golem, and their arch-rival, a robotic Nazi dinosaur. In short, don't expect this comic to make any damn sense whatsoever.
In this story, the Boy King — who resembles Prince Valiant crossbred with He-Man crossbred with the Burger King mascot — and his giant Swisslakian golem are helping the Americans mine for ore. The Nazis are infuriated by Boy King and his innovative golem-centric ore-procuring techniques, so they build a massive mechanical dinosaur for no apparent reason.
Since Boy King is chilling in America, the T-Rex shimmies across the ocean to do battle. Please note the US military's sterling skills of deduction in the lower right panel.
