[Paris: Le Terrain Vague/Editions du Scorpion, 1957]. A portfolio of 42 mostly abstract semi-erotic drawings based on the Oedipus legend, each within a captioned bifolium with die-cut window through which the illustration is visible. Boullet's work, produced throughout the post-war era, focused on gay themes, often in an erotic context. A charming work in an unusual format. Reprinted in 1958 by the same publisher, but the first edition is notably scarce; only 2 locations noted in WorldCat, few in trade. First trade edition of 425 copies, this copy not numbered (apparently as usual). Octavo; 43 folded, die-cut leaves laid loose within pictorial wrappers. Faint ring-stain tolean and unmarked in original wrappers; Very Good.
