Blades front-of-shirt sponsor John Holland celebrated their 40th anniversary by hosting a special event at their showroom on Meadowhall Road.
Sheffield United manager Nigel Clough was on hand to officially open the event and he was joined by John Brayford, Terry Kennedy, Paul Coutts, Jose Baxter, James Wallace, Matt Done, Louis Reed, Che Adams and coach Chris Morgan.
Councillor Talib Hussain, Deputy Lord Mayor, was also in attendance.
The evening saw a speech from owner Mark Holland, who took sole charge of the business following his father John's retirement in 2011, as well as a £1,000 cheque presentation from both John Holland and Cardiff-based Moto Novo Finance to go towards The Children's Hospital Charity's Make It Better campaign.
Business owner Mark Holland said: "It gives us great pride to look back on the achievements of John Holland since our establishment in 1975.
"The evening was a wonderful way to mark our 40th year and at the same time bring together people from the Sheffield City Region. I'd like to thank everyone who attended and joined us in celebrating this major milestone."
Blades manager Nigel Clough presented a plaque on behalf of the Club to commemorate John Holland's 40th anniversary.
He said: "I'm delighted to have been a part of this special occasion to celebrate 40 years of this great Sheffield family business.
"It's wonderful for us to have John Holland on our Sheffield United shirts as we fight for promotion to the Championship and on behalf of the Club we congratulate them on this wonderful achievement of 40 years in business."
John Holland claimed one of the motoring industry's biggest national awards when they were named 2014/15 Dealers' Dealer of the Year at the Car Dealer Magazine Used Car Awards.
The company's twenty thousand feet showroom, which sees around 150 quality, luxury and prestige vehicles a month, has recently seen an extensive refurbishment including a new reception area, and work is currently underway on a state-of-the-art workshop and MOT and servicing department.
