Story Locks! ?
Considered rare and highly collectible, story locks were made in the late 19th century and featured intricate pictures on both sides. Some story locks depicted images of people, often in bizarre locations or positions, where the mouth would be the keyhole.
Though it is rare to find antique locks available with their key, the lock alone may sell for $1,000 or more depending on its condition and collector.
