Signed Franco Mastantuono 30 Real Madrid 2025-26 | Beckett Grade 8

Beckett graded this signature 8 out of 10 on Franco Mastantuono's Real Madrid shirt, signed on the back, on the number, size L, and recorded as his first Beckett certification. The signing itself took place in Madrid, Spain, on 26 August 2025.

The shirt

Adidas made this Real Madrid home shirt for the 2025-26 season in white, cut to the club's Slim Fit specification and marked size L on the inside neck label. The shirt remains in excellent condition, with the original tags still attached, a Fanshop Match shirt built to the same specification as the shirts worn on the pitch, sold through the club's own official channels for that same season.

Authentication by Beckett

Beckett issued certificate BV09683 for this signature, backed by a certificate of authenticity, a letter of authentication, and a grade of 8 out of 10. The shirt also carries an Iridescent Hologram Disc sticker, sealing the signature to that specific certificate. A collector can check the certificate number, the letter and the hologram directly against Beckett's own published record, independent of anything Walkouts states.

The signing

Walkouts recorded this signing directly: proof code 25FMA20027630 ties the shirt to the same 26 August 2025 session in Madrid, Spain. Mastantuono is pictured at that session, in an Argentina training top, mate gourd and bombilla in hand as he looks over the black number cutouts against the red wall, and that proof code is what a collector holds against Walkouts' own record of the day.

For the collector

Before this, Mastantuono had already come through Argentina's under-20 side and Club Atlético River Plate in 2025, then earned his first senior Argentina call-up and the move to Real Madrid, playing as an attacking midfielder and forward. This signed shirt anchors a collector to that same arc, the River Plate player turned Real Madrid player, born 14 August 2007, who first wore Argentina's colours at under-17 level back in 2023.

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.
