According to BBC News, the archive also contains a letter from comedian Spike Milligan, who offers to do laundry in exchange for a job. Lester was instrumental in adapting radio comedy programme 'The Goon Show' for television, in the 1956 series 'The Idiot Weekly, Price 2d'.
Lester's success with the Fab Four made him a mainstay of the Swinging 60s scene. The director later found box office success in Hollywood, directing Christopher Reeve in 'Superman' and Oliver Reed in 'The Three Musketeers'.
His donation is his way of returning something to the industry that gave him so much recognition. "The organisation has always been very helpful to me," said Lester. "It is a pleasure for me to be able to offer them the detritus of my working life," he added.
