It's a Small World
It's a Small World in the Magic Kingdom is different from every other version in the world. It is the only version with the classic facade and clock tower fully inside and not as the exterior of the ride. It is also the only version still left in its original state without Disney characters.
If you want to see the ride as it was in the 1964 World's Fair, beyond the Disneyland original (Which was the World's Fair version, just now with Disney characters) this is how to do it as it has had very few changes since it opened.
