Players included in this lot are Andy Frederick inscribed "SB XX" *** Keith Van Horne inscribed "SB XX" *** Keith Ortego inscribed "SB XX Champs" *** Tom Thayer inscribed "Super Bowl XX". The Andy Frederick mini helmet has a COA from a third party we are not familiar with (mikessportsnmore) and is being sold "AS IS". None of the other three signatures have a third party COA and are being sold "AS IS".
