P.T. Barnum leads a parade of 21 elephants across the Brooklyn Bridge
The bridge had opened just a year earlier. Ostensibly, the stunt was meant to demonstrate the strength and stability of the bridge, which at the time of its completion was the longest suspension bridge in the world and the tallest structure in the western hemisphere. As a convenient side effect, the parade of elephants also served as a promotion for P.T. Barnum's circus and his star elephant, Jumbo.
