This very rare doll from the early nineteenth century demonstrates a very innovative design for its day: a spoked wheel of legs which allow the doll to ‘walk’ when it is pushed across the floor.

The doll would have originally been costumed in a long dress to hide the leg mechanism, so only two walking feet would have shown at a time.
