Illustrations by Jean-Claude Forest
Prior to creating Barbarella in 1964, Jean-Claude
Forest had already distinguished himself as a science fiction illustrator
by contributing numerous covers to the magazine Fiction
(the French edition of F & SF) and
the paperback imprint Le Rayon Fantastique.
Shambleau, which had first appeared in the anthology Escales dans l'Infini (edited & translated by G. H. Gallet, Rayon Fantastique, 1954), was reprinted in the Summer 1955 issue of V-Magazine (which later published Barbarella as well), with numerous illustrations by Forest.
