Curtain finally falls for 'greatest show on earth' after 146 years

The clowns, animal acts and acrobats of the Ringling Bros and Barnum & Bailey Circus took their final bow at an arena outside New York on May 21. The final show was a sell-out with about 17,000 people in attendance – it ended nearly 150 years of the famous circus and with a predicted 250 million attendees over the years.
