New York edition
London edition
Mark Twain released "Huckleberry Finn" in London through Chatto & Windus in December 1884, just before Charles Webster released the U.S. edition in February 1885. The step gave him an English copyright that prevented pirates from reproducing the book and cutting into his profits internationally.
The University of Virginia's Clifton Waller Barrett collection owns both a London and a New York first edition.
