If you were a filthy rich kid in Russia a century ago, this would have been the ultimate toy. The famous goldsmith Israel Rouchomovsky made it between 1892 and 1906 with all the features a child could want:
the fully articulated human skeleton in a velvet-lined coffin chased around on each side with three panels showing the course of life, one end with attributes of the arts, the other with attributes of war, the removable cover with the journey in the footsteps of the Angel of Death, surrounded by the faces of infants alternately laughing and crying.
See? It's educational as well as fun.
