The tennis champion Roger Federer has become the first Swiss national alive to be honoured through a stamp issue.
Roger Federer has become a living symbol of Switzerland
The new stamp, valued at one Swiss franc (£0.4; $0.8), shows a smiling Federer holding the Wimbledon trophy.
Switzerland has traditionally shunned personalities on its postage stamps, except for historical figures.
Federer, ranked number one in the world, has won four straight Wimbledon titles, 10 Grand Slam titles and 47 singles titles since 1998.
"It's a great moment. I'm proud to be a symbol like the army knife or the mountains," Federer, 25, said at the unveiling ceremony for the stamp in Basel, the capital of his native region.
