 The Black Island was first serialised in Le Petit Vingtième from 15 April to 16 November 1937 under the title Le Mystère De L 'Avion Gris ( The Mystery of the Grey Plane ) . From 17 April 1938 , the story was also serialised in the French Catholic newspaper , Cœurs Vaillants . In 1938 , Éditions Casterman collected the story together in a single hardcover volume , publishing it under the title L 'Île noire ( The Black Island ) . Hergé however was unhappy with this publication due to errors throughout , most egregiously that the front cover omitted his name .
