Stellar keepsake from the "old" Yankee Stadium in this blue plastic seat back, signed by slugger Alex Rodriguez. Piece measures 18x15" and the plate indicates that the seat number is Mickey Mantle's "7." A sticker on the bottom reads, "Yankee Stadium, April 18, 1923 - September 21, 2008." An engraved plate adds the important distinction that this is after the 1972 stadium reconstruction, before which the seats were wood. Plate reads, "OLD YANKEE STADIUM Seat Back - 1973-2008 - Auto by Alex Rodriguez (ARod)." The black Sharpie autograph has somewhat faded, grading 5/10, and the seat shows great use overall.
