This 10x16 Hoosiers poster is signed by Maris Valainis. Valainis starred in the hit-movie as Jimmy Chitwood, who hit the game-winning shot to win the Indiana state high-school championship. Take home a piece of movie history with this signed Hoosiers poster! It includes a Steiner Sports Certificate of Authenticity and accompanying tamper-evident Steiner Hologram. The Steiner Seal Means It's Real.
