Tiger triplets born at the Lincoln Park Zoo in Chicago on July 16, 1956. The photo was taken on September 11, 1956 as they romp and play on the photographer's camera bag.

"Lincoln Park Zoo has one of the finest "vintage" feline house's of any American zoo. "Back in the day" you could close your eyes and take in the smells, the echo's, and dampness and know in an instant you were in the lion house. It has been modernized and rehabbed into something special."
