Mario Kempes Signed Argentina 1978 Retro Home Shirt

Every signed item comes with an Iconic Shirts Certificate of Authenticity (COA) featuring a unique certificate number.

Simply enter this number in our online Certificate Verification database to view the authenticity information and details registered for your item.

If a product comes with different or additional third-party authentication, this will be clearly stated on the product page and certificate.

Often, yes. Shirts signed at our own private signing sessions come with a signing photo, and many other pieces include photographic proof of the signature. Where that proof exists it is listed with the product or sent with your order, and if you cannot see it on the page you are welcome to ask us for it before you buy.

We sell signed club and national team shirts spanning the 1980s to the present, alongside signed boots and signed photos. Some are official retro or officially licensed replica shirts and others are current-season shirts — the exact type is named in each product’s title and description, so you always know what you are buying. What is the same on every piece is the signature: hand-signed in person and certified.

The price follows the piece rather than a fixed rate. The player, the era, how rare the shirt is and how the signature was obtained all move it, and framed pieces cost more than loose shirts because of the frame itself and the secure packaging they need. Certification plays a part as well: third-party authentication by a house such as Beckett or PSA/DNA is a separate process from our own in-house certificate.

We sell them as collectibles, not as financial products, so we make no promise about what a shirt will be worth later. What we can say is that collectors look for exactly what we document on every piece: a genuine hand-signed shirt, a Certificate of Authenticity, a serial number that can be checked, and a signing photo or third-party authentication where one exists.

Yes — tell us the player, the club and the season you are after and we will let you know what we have. Our stock changes regularly and we arrange our own private signing sessions, so a piece that is not on the site today may still be possible. Send us the request and we will come back to you.

Yes. Every signed item is sold with a Certificate of Authenticity, usually carrying a unique serial number attached to the shirt, an additional certificate, or both. The certificate is issued either in-house by us or by a third-party authenticator such as Beckett or PSA/DNA, and the number on it is what you use to verify the piece in the official database.
