Signed Samuele Inácio Dortmund 2024-25 | Fanshop Authentic KidSuper

Beckett graded this signature 9 out of 10, on Samuele Inácio's Borussia Dortmund 2024-2025 KidSuper edition shirt, size L, on the back, below the number. Inácio signed it on 17 March 2026 at Manchester Airport, Manchester, England, with the signing documented on video.

The shirt

Puma made this Borussia Dortmund shirt as the 2024-25 KidSuper edition, a collaboration between the club and the streetwear-rooted design studio behind the project, with the original tags still attached and the item in excellent condition. The design keeps Dortmund's yellow and black club identity while layering in KidSuper's own creative visual language, a genuine period piece from the collaboration's own season rather than a later reissue.

Authentication by Beckett

Beckett issued certificate AG004057 for this signature, documented with a certificate of authenticity, a letter of authentication, and a grade of 9 out of 10. A One Beckett Medallion hologram sticker seals the signature to that specific certificate, keeping this signed football shirt and its paperwork tied together. A collector can check the certificate number, the letter and the hologram directly against Beckett's own published record.

The signing

Walkouts recorded this signing directly: proof code 26SIN20032040 ties the shirt to a session at Manchester Airport, Manchester, England, on 17 March 2026. Inácio is seen signing the shirt with a black pen against the yellow fabric in the capture, and that proof code is what a collector holds against Walkouts' own record of the session, rather than taking the claim on trust.

Borussia Dortmund at 2025 FIFA Club World Cup

Borussia Dortmund reached the quarter-finals of the 2025 FIFA Club World Cup, the newly expanded 32-club edition of the tournament, eventually losing 3-2 to Real Madrid at MetLife Stadium in New Jersey. This KidSuper edition shirt carries the same club identity Dortmund wore through that run, a design tied to the 2024-25 season in which that Club World Cup campaign fell.

For the collector

Inácio was born in 2008, making him one of the younger names to carry Borussia Dortmund's shirt into a collaboration piece like this one. The shirt is a period original from the 2024-25 KidSuper collaboration itself, and the autograph on it dates to that same era, an early-career signature on a shirt tied to a specific, one-season design rather than the club's ongoing standard kit.
