The Pickwick Papers

The Posthumous Papers of the Pickwick Club (also known as The Pickwick Papers) was Charles Dickens's first novel. Because of his success with of Sketches by Boz published in 1836 Dickens was asked by the publisher Chapman & Hall to supply descriptions to explain a series of comic cockney sporting plates by illustrator Robert Seymour, and to connect them into a novel. The book became Britain's first real publishing phenomenon, with bootleg copies, theatrical performances, Sam Weller joke books, and other merchandise.
Seymour's widow claimed that the idea for the novel was originally her husband's, but Dickens strenuously denied any specific input in his preface to the 1867 edition: "Mr Seymour never originated or suggested an incident, a phrase, or a word, to be found in the book."
