In 1828, the critic John Payne Collier published a Punch and Judy script under the title "The Tragical Comedy or Comical Tragedy of Punch and Judy". The script was illustrated by the well-known caricaturist George Cruikshank. Collier said his script was based on the version performed by the "professor" Giovanni Piccini in the early 19th century, and Piccini himself had begun performing in the streets of London in the late 18th century. The Collier/Cruickshank "Punch" has been republished in facsimile several times. Collier's later career as a literary forger has cast some doubt on the authenticity of the script, which is rather literary in style and may well have been tidied up from the rough-and-tumble street-theatre original.
