The "Cockney" Bateman was originally published as a small book in 1839, with illustrations by George Cruikshank. The text and "scholarly" notes were anonymous, but are generally considered to have been a collaboration between Dickens and Thackeray. The book was reprinted many times (and, of course, the text pirated on broadsides) and copies frequently turn up in second hand book shops. My copy is an 1883 reprint.
