The Great Alaskan Land Rush

When the last surviving heir of the Russian Imperial Alaskan Colony Company shows up and claims to own Alaska, the Joes suspect it is a Cobra plot to wrench away America's largest state. The only way to disapprove the claim is for the Joes to go to Alaska and find the colony's Imperial Seal. Three problems: the seal has been missing for over a hundred years, the Russians are looking for the seal so they can reclaim Alaska, and Cobra is determined to stop them both!
