An unusual collectible, this plastic Yankee Stadium seat back is signed by four men who provided countless wonderful moments while sitting against it. Known as the "Core Four," Pinstripe great Derek Jeter, Mariano Rivera, Andy Pettitte, and Jorge Posada have lent their signatures, only slightly faded, in blue marker. The seat has a plate with the number "5" and shows classic and expected wear. Comes with JSA sticker and holograms from MLB and Steiner.
