 The St John logo appears on the right door of several models of the TARDIS in the long-running British series "Doctor Who".This was copied from British police telephone boxes, from the 1970s and earlier, the larger versions on which the TARDIS is modelled contained a folding canvas stretcher and a first aid kit provided by St John Ambulance.These boxes pre-dated universal radio communication and enabled both patrolling police officers to contact their station and members of the public to call for assistance.
