This is a framed Powder Blue Nike Los Angeles Chargers Jersey, approximately 31x36 with the frame, that has been hand signed by Justin Herbert. This item has been witnessed and certified authentic by Beckett Authentication (BAS) and comes with their tamper-proof witness sticker. Beckett Authentication has recently changed their physical certificate card policy where they no longer match their tamper-proof sticker with a physical certificate. A certificate can be printed on Beckett's website for the matching authentication number.
