Abstract
A display device wherein a decorative ornament is mounted on a drive plate that is driven by a windup music box drive mechanism through a transmission assembly so that rotation of the drive plate in a first direction winds up the drive mechanism which, during unwinding and the production of music, causes the drive plate and ornament to rotate in a second opposite direction.
