Two white cards signed in person by comedians Ronnie Barker (1929 - 2005) and Ronnie Corbett (1930 - 2016), stars of The Two Ronnies, the  British television comedy sketch show which aired on BBC1 from April 1971 to December 1987. The usual format included sketches, solo sections, serial stories and musical finales.

The two Ronnies met in 1963 at the Buckstone Club in the Haymarket, London, where Corbett was serving drinks between acting jobs. At the time, Barker was beginning to establish himself as a character actor in the West End and on radio. They were invited by David Frost to appear in his new show, The Frost Report, with John Cleese, but the pair's big break came when they filled in, unprepared and unscripted, for eleven minutes during a technical hitch at a British Academy of Film and Television Arts awards ceremony at the London Palladium in 1970. In the audience was Bill Cotton, the Head of Light Entertainment for the BBC, and Sir Paul Fox, the Controller of BBC1. Cotton was so impressed by the duo that he turned to Fox and asked: "How would you like those two on your . network?" Unknown to them the pair had just had the renewal of their contract declined by rival network ITV, and so were free to change channels. Barker and Corbett were given their own show by the BBC. The programme became one of the most successful and long running light entertainment shows on British television, broadcast in the prime-time slot of 8 p.m. on a Saturday night, and at its peak, was watched by 18.5 million viewers a show. Following the departure of Morecambe and Wise from the BBC in 1978, The Two Ronnies became the BBC's flagship light entertainment programme, regularly gaining the top viewing figures in the critical Christmas Day audience battle.
