Input: Question: How long did the quarterback who had his photo taken after a defeat at Pitt Stadium play for the New York Giants? Passage:The NFL's Steelers played home games at Forbes Field from their 1933 inception to 1957. They first played at Pitt Stadium in 1942, in an exhibition match for U.S.O. charity against the Fort Knox "Armoraiders" on November 15. From 1958 to 1963, the Steelers split home games between Forbes Field and Pitt Stadium. Fans were able to purchase season ticket packages for one site or the other. In 1964, the Steelers began to play home games exclusively at Pitt Stadium, which they continued until moving to the new Three Rivers Stadium in 1970. Of historic note, the iconic photo of New York Giants quarterback Y. A. Tittle, helmet-less, bloodied and kneeling, was taken at Pitt Stadium in 1964 following a Giants' loss to the Steelers on September 20. The photo, taken by Pittsburgh Post-Gazette photographer Morris Berman, now hangs in the Pro Football Hall of Fame.
