This Don Mattingly autograph is guaranteed authentic and includes a Steiner Sports Certificate of Authenticity and an accompanying tamper-evident Steiner Hologram. The Steiner Seal Means It's Real. It also includes a Hologram from MLB Authentication. Steiner Sports is the Official Memorabilia Partner of the New York Yankees.
