* The Little Golden Key: Alice finds a tiny golden key, which she later discovers fits a tiny door in the wall. This is a significant object in the story, leading her to the rabbit hole and the beginning of her adventures.
* The Doorway to Wonderland: The door itself that leads to Wonderland is important. It is often depicted as a small, wooden door with an elaborate doorknob, but the doorknob itself isn't a prominent character or object.
