This product page includes actual photos (screenshots) from the page accessible via the QR code. [The following is a direct translation from the PIA official page.] Players Ink Authentication (PIA) is an authentication company that authenticates only with witnesses. This means that a PIA service representative witnessed the autograph being signed, guaranteeing 100% authenticity. Special tamper-proof holograms are used to easily identify these items as PIA, and all relevant information necessary for verification is reflected in the online database. Furthermore, a JSA representative also attended this event, so the jersey comes with a certificate of authenticity that can be verified on the JSA website. * JSA is a top-class authentication company with a strong reputation in the United States. * Serial numbers and QR codes are hidden to prevent copying.
