Much emphasis is often placed on the first printed script of Punch and Judy, in 1827. It was based on a show by travelling performer Giovanni Piccini, illustrated by George Cruikshank, and written by John Payne Collier. This is the only surviving script of a performance, and its accuracy is questioned. The performance was stopped frequently to allow Collier and Cruikshank to write and sketch and, in the words of Speaight, Collier is someone of whom "the full list of his forgeries has not yet been reckoned, and the myths he propagated are still being repeated. (His) 'Punch and Judy' is to be warmly welcomed as the first history of puppets in England, but it is also sadly to be examined as the first experiment of a literary criminal."
