This is the signed and numbered clothbound edition with an extra 8 pages containing an essay by Charlier and an interview with Jean Giraud and an extra color plate (unsigned) which is laid in.
#594 of 2,050 copies signed by both Charlier and Gir.
This oversize black & white edition of Blueberry #22: Le Bout de la Piste (published in English as The End of the Trail) is "as close as one can get to Giraud's originals." The reproduction is excellent.
"De merveilleux dessins en noir et blanc, tout proches de l'oeuvre original de Giraud."
