Each of our signed memorabilia products comes with a certificate of authenticity (COA), guaranteeing that what you purchase is authentic. Each item also comes with a lifetime guarantee of authenticity. This signed Lionel Messi shirt comes complete with a reflective hologram label. The unique number is shown on both the label and COA (certificate of authenticity), linking the COA and autograph together. We personally obtain all of our signatures at signing events, sporting grounds and auctions and ensure their authenticity is 100% genuine. Please note autographs maybe different to the one in the picture as we often have multiple shirts signed.
