Germany/Iceland] Journey to the Center of the Earth by Jules Verne. Illustrations by Riou. Paris, Bibliothèque d'Éducation et de Récréation, J. Hetzel Éditeur, 1867. Large single in-8°. Publisher's full ultramarine blue and "rose bouquets" cardboard of the 2nd type. Spine called "with stars". Combed endpapers. Charles Magnier bookbinder. Printed by Jules Bonaventure. First illustrated edition and first single hardback. A few tiny discolorations on the first board. Covers and corners very slightly rubbed. Otherwise, a very nice copy of this rare volume, with a perfect interior and, here, in its most coveted colour. This volume makes a perfect pair with lot n°98. The characteristics of the spine ("au semis d'étoiles") are only found for this title and Cinq semaines en ballon, whose first enlarged edition in-8° appeared the same year. Hetzel will abandon the "star-sown" spine in the months following its publication.
