It’s been a Rocky road. After being labeled not art but a mere movie prop, the enormous (9′ 11″, 1300 pounds) statue of Sylvester Stallone as Rocky Balboa was shunted from museum steps to sports stadium to warehouse to, finally, the museum again. Not, this time, at the top of the massive stairs leading to the Philadelphia Museum of Art where the fictional boxer once pranced triumphant, but somewhere at the bottom. Stallone had commissioned the statue 25 years ago for a scene in Rocky III. “This is mind-bending to me that this could happen,” he said at the unveiling on Friday. “The statue being here is not about me. It’s about you, because inside every one of you there’s a real Rocky.” Well, that’s a relief; we thought that was a tumor.
