The eccentric Elliott collection has a focus on early 20th-century technology, and for good reason – the museum was founded by Harmon Elliott, the son of Sterling Elliott, who invented the kingpin and steering knuckle (which led to steerability for four-wheeled vehicles). Hence the spectacular collection of vintage vehicles, displayed in a $20 million gallery complete with robotic racking system, which ferries cars to the foreground and rotates them for viewing.
Other collections segue bizarrely from a 1911 Pelican hydro-airplane and a collection of outboard motors to artifacts detailing the history of prominent Martin County citizens. There's also one of the largest collections of autographed baseballs and baseball cards in the country.
