Mathis Albert 41 Borussia Dortmund 2025-2026 Signed Football Shirt

Beckett graded this signature 8 out of 10 on Mathis Albert's Borussia Dortmund shirt, a Fanshop Match piece from the 2025-2026 season, the first Beckett-certified example of his autograph, signed on 17 March 2026 at England, Manchester, Manchester Airport, size L, and independently verifiable through Beckett's own certificate.

The shirt

This is Borussia Dortmund's 2025-2026 home shirt in yellow and black, made by Puma, carrying Albert's signature on the back, beside the number. The shirt remains in excellent condition with its tags still attached, a size L. This Fanshop Match tier is produced to the same construction quality as the shirt worn on the pitch that season.

Authentication by Beckett

Beckett has certified this signature under certificate AG004063, with a grade of 8 out of 10. Beckett Authentication Services examines each signature against a Video Spectral Comparator and an extensive exemplar database, led by authenticators with decades of experience in the field, and a collector can confirm the certificate directly through Beckett's own online database.

The signing

Walkouts witnessed this signature directly, on 17 March 2026 at England, Manchester, Manchester Airport, with the moment captured independently of the certificate above. The session carries its own Walkouts proof code, 26MAB20031741, tying this specific shirt to that recording, and a collector can check it against the watermarked stills of the video proof, not against a description of it.

2025-26 Season at Borussia Dortmund

This is Albert's 2025-2026 season at Borussia Dortmund, the year this signed shirt belongs to. It is played in the Bundesliga, the competition this shirt's signature is tied to. Albert was included in Dortmund's squad for the 2025 FIFA Club World Cup, the youngest player at the tournament at 16 years and 27 days. Born on 21 May 2009, he plays as a winger and wide attacker, naturally right-footed, a rare young talent already on the club's biggest stage.
