This black metal turnstile with a foot pedal is made of four horizontally revolving arms, and is one of five known to exist. It measures 42" wide from arm to arm and is 41" tall. The accompanying plaque measures 8 x 10", and reads, "Original Turnstile, (One Of Only Five), Connie Mack Stadium, Circa 1909." It is missing the top cover, and is an excellent piece of baseball history from Philadelphia.
