Signed Mathis Albert 41 Dortmund 2025-26 Away | Fanshop Match

Beckett graded 9 of 10 on this Mathis Albert Borussia Dortmund 2025-26 away signed shirt, independently verifiable through Beckett Authentication Services. This is Albert's first Beckett certification, the first record of his signature in Beckett's database. The signature sits on the back, beside the number.

The shirt

This is the Fanshop Match specification of Borussia Dortmund's 2025-26 away kit, made by Puma in the club's yellow and black away colourway, size L, distinct from the home shirt. The shirt is in excellent condition with its original tags still attached. A Fanshop Match shirt is made to the same specification as the shirt worn on the pitch, without being worn in any competitive match itself.

Authentication by Beckett

This authentication carries certificate AG004062 from Beckett, documented with a certificate of authenticity, a letter of authentication, and a grade of 9 out of 10. The shirt also carries a One Beckett Medallion hologram sticker, tying that certificate directly to this exact item, evidence a collector can check independently through Beckett's own database rather than take Walkouts' word for it.

The signing

Walkouts recorded this signature at Manchester Airport, Manchester, England, on 17 March 2026, with Albert photographed signing the shirt, its crest and number 41 visible in the frame. The Walkouts proof code 26MAB20031941 ties this documentation to this exact item, independently verifiable at any time, the same record a collector can hold up against the shirt itself to confirm it firsthand.

For the collector

Albert carries a marker of a wider stage: selection in Dortmund's 2025 FIFA Club World Cup squad, where at 16 years and 27 days he was the tournament's youngest player. Born on 21 May 2009, he plays as a winger, a wide attacker who is naturally right footed. A signed shirt from this 2025-26 away season is a stake in that early trajectory, held before the rest of the story is written.

What You Receive: The Signed Shirt

You receive the signed shirt, exact video proof of signing, sent unwatermarked after purchase, a certificate of authenticity, and a letter of authentication.

Why Walkouts

We hand you proof you can check without us. Authentication from the names collectors already trust, our own signing proof captured the moment the marker touched the shirt, and the full chain behind both, so your certainty rests on evidence you hold yourself. We've bought fakes. We know that feeling, and we built Walkouts so you never have to.
