The 50th anniversary of Ronnie Delany's Olympic medal feat is to be commemorated in a special edition stamp.
The new 48 cent stamp features Delany's return to Dublin after winning the Gold Medal in the 1500 metres at the 1956 Melbourne Olympics.
Delany, who attended the launch of the stamp in Dublin's GPO with members of his family, said: "It is a singular honour to be featured on a stamp in my own country, celebrating my Olympic achievement as an Irishman some 50 years ago.
"I feel a deep sense of appreciation to An Post, the Irish Government and all those connected with the design and production of this emotive stamp."
Delany overcame the home favourite John Landy on the last lap to win the Gold Medal in the 1500 metres and set a new Olympic record in the process.
He became the first Irishman to win an Olympic athletics title since Bob Tisdall in 1932.
Minister for Communications Noel Dempsey said: "I am delighted to launch this stamp celebrating Ronnie Delany's Olympic win 50 years ago.
"In an era of saturation sports coverage and international live sports events at our fingertips, it is hard to imagine the impact that Ronnie's sprint to victory would have had on that memorable day 50 years ago."
The new stamp features a painting by Dr Thomas Ryan RHA which was completed in 1957 after his triumphant return to Dublin. It depicts the runner in front of Irish tricolour adorned with the Olympic rings.
The stamp, which was designed by Steve Simpson, is available from main post offices and the GPO in Dublin.
