Vingt mille lieues sous les mers (Twenty Thousand Leagues Under the Seas)

No book-club edition bears on identifying the 19th-century first. Modern-market pitfall instead: the vast majority of "Hetzel" copies offered are later re-issues of the Voyages Extraordinaires in the "aux deux éléphants" cartonnage (from 1875, standard to ~1891) or still-later Hetzel/Hachette printings — these are NOT the 1871 first. In English, essentially all common copies are 20th-century reprints of the flawed Mercier text (Everyman, Scribner, book-club / Junior Deluxe reprints, etc.); the only first is the Sampson Low edition (printed 1872, title-page 1873). Reprint/re-issue status is diagnosed by the binding plate and imprint, not by the color of the cloth.
