Seat back, from an original Three Rivers Stadium seat, signed in black Sharpie by two iconic Pittsburgh Steelers players: "Mean Joe" Greene and Rocky Bleier. Both have added inscriptions with their signatures. Greene has written "3 Rivers Stadium/Steel Curtain," while Bleier has added "4X SB Champs." Greene's inscription is especially notable as we cannot recall having ever seen him add "Steel Curtain" to other pieces he has signed. Both the signatures and inscriptions are boldly rendered and grade 10/10. The plastic seat back, which is numbered "13," measures 18.5x15.5" and is in Excellent condition. Please note: the size and/or weight of this lot will necessitate an increased shipping charge.
