The opening prologue of the film, shows the undertakers emptying a body out of its casket before throwing the body into the grave then heading home with the now re-usable coffin. The hearse coach that was used at the beginning of the film, now resides at the Haunted Mansion at Disneyland. It was black in the film, but has since been painted white.
Here it is decorated with the Nightmare Before Christmas holiday overlay.
Growing up in Los Angeles in the 70s/80s we visited Disneyland on a regular basis and often after school, before "Annual Passes".
