Cullis captained both England and Wolves during a successful playing career, before becoming the club's greatest ever manager, bringing the Football League title to Molineux three times and winning the FA Cup twice.
In honour of Cullis, Richards and Gough travelled to Cambridge Road Primary School in his hometown of Ellesmere Port, in Cheshire, to take part in an unveiling ceremony, where the pair were joined by Cullis’ son Andrew and outgoing PFA chief Gordon Taylor.
Pupils Charlotte O'Toole and Logan McLoughlin joined the iconic former Wolves striker Richards in helping to pull the curtain down and reveal the blue PFA plaque next to the school entrance.
Gough said it was a “real privilege” to attend the unveiling, adding: “Few men made a greater impact in football than Stan Cullis. Ferenc Puskas described him as the most classical centre half of his generation.
“My father used to take me to Molineux. I sat right opposite the tunnel. I remember as an 11-year-old he was the most animated manager.”
An exhibition centred around Cullis’ journey and career – as well as details about another Ellesmere Port footballing legend, Joe Mercer – was on display in the school hall ahead of the unveiling.
Richards, who is also chairman of the Wolves Former Players Association, described the exhibition put together by the children as “absolutely magnificent”, saying: “In Wolverhampton, Stan is remembered with pride and affection. He is a hero. His record is unsurpassable.”
Cullis’ son Andrew, who travelled from Bournemouth with his wife Elizabeth to attend the ceremony, said: “I'm very grateful to this school for what it gave my dad. He was the youngest of ten children, his mum was in a wheelchair and his dad wasn’t terribly well either.
“Coming here really helped him and he learned a love of reading. When he was older, he went to night school and learned languages, bookkeeping and shorthand.
“He was captain of the school team and went on to play for Ellesmere Port Wednesday. I understand they were called this because the shops used to shut on a Wednesday afternoon, and it was the only time they had to play.
“In 1960, he brought the FA Cup to Oldfield Road, along with a few Wolves players, to show his mum and dad and the neighbours. I’m not sure you can do that now – put the FA Cup in your car and take it home.”
