Martina Navratilova to launch Art Grand Slam exhibition in Prague

Czech-born tennis star Martina Navratilova will be opening an exhibition named Art Grand Slam in Prague next week. The project, initiated by Slovak artist Juraj Kralik, combines tennis and art and will be on show at Prague's Congress Centre. Mr Kralik paints pictures onto which Martina Navratilova then creates patterns by hitting them with paint-covered tennis balls.
