This 16x20 photo is personally hand-signed by former Knicks great Charles Oakley. He was a member of the Knicks Core consisting of Patrick Ewing, John Starks, and Mark Jackson. A defensive specialist, Oakley will always be remembered for his tenacity and in-your-face defense. Take home a piece of Knicks history with this signed Charles Oakley photo! It includes a Steiner Sports Certificate of Authenticity and accompanying tamper-evident Steiner Hologram. The Steiner Seal Means It's Real.
