It shows numerous "human curiosities", among them members of different ethnic groups in their traditional attires being presented on a large stage. The captions read: "The Barnum & Bailey Greatest Show on Earth – the peerless prodigies of physical phenomena and great presentation of marvelous living human curiosities – the world's largest, grandest, best amusement institution."
