The signature is in Silver Paint Pen. This jersey was signed at a private signing with us and would make a great addition to any Packers collection! The jersey size is XL and all letters and numbers are sewn in. This autograph is guaranteed to be 100% authentic and will include a COA hologram from Beckett authentication. We have been in business for over 40 years and are frequently featured on Signings Hotline as well as SCD. We specialize Green Bay Packers, Milwaukee Brewers, Milwaukee Bucks, Milwaukee Braves, Wisconsin Badgers and Hall of Fame autographed memorabilia. Thanks for looking we appreciate your business.
