Mr Horne began collecting sports memorabilia in 1995, the same year he founded the construction and scaffolding firm, part of the JR Group.

What started as a few signed football shirts bought at charity auctions has evolved into one of the most extensive private collections of its kind in Scotland, featuring legendary names from across the globe.

To mark the company’s milestone year, Mr Horne is auctioning more than 130 treasured items to raise vital funds for the Emmie Smillie Foundation and MND Scotland.

Among the highlights going under the hammer are signed shirts from Graeme Souness, Ronaldo, Jimmy Johnstone, Brian Laudrup, and Lionel Messi; iconic framed photos autographed by Diego Maradona, Peter Shilton, and George Best; and an array of rare boxing and golf memorabilia, including items signed by Muhammad Ali, Tiger Woods, and Masters champions.

The auction, organised by event specialists Blue Parrot Events Group through their Event PAL fundraising platform, will be hosted online and live for two weeks from today, giving fans and collectors the opportunity to own pieces of sporting history while supporting meaningful causes.

Mr Horne said: “This journey started with Old Firm memorabilia and a desire to support good causes.

“Over the years, I’ve been lucky to acquire pieces from some of the biggest names in sport. Every item holds a story, a moment, a memory, and while it’s emotional to part with them, this feels like the right time.

“Giving back has always been part of our company’s DNA, and this is my way of doing something personal to honour that as we hit 30 years.”

He added: “The auction will raise funds for the Emmie Smillie Foundation, a tribute to a wonderful young girl taken far too soon. Her dad, Andy Smillie, helped us start our company and our families remain close friends.

“We’re also supporting MND Scotland, in memory of Aaron Souttar, another young life lost too early. His parents, Jack and Heather, are dear friends also.”

With something for every sports enthusiast, Mr Horne hopes the collection will find passionate new owners and raise a significant sum for two very special charities.
