One of City’s all-time best goalkeepers, Graeme had 2 spells with the club between 1971 and 1980, making 280 appearances.
His first two seasons saw City survive in Division Three on goal average.
The next season however, Graeme equalled a Football League record of 11 successive clean sheets as City won promotion in 1974 to Division Two (now known as The Championship); along with Chris Topping, Graeme was an ever-present across both Division Two seasons.
Speaking on becoming a Club Ambassador, he said: “Just wanted to say thanks for asking me to be an ambassador.
“City was a special club for me and I played in a good team with a great set of lads.
“One of the reasons I would like to do this is to put something back into the club that gave me so much pleasure.”
