Land of Black Gold
At the request of Hergé's British publisher, Methuen, in 1971 he made a range of alterations to the "Land of Black Gold", transferring the setting from the British Mandate for Palestine to the fictional state of Khemed. As with the revised edition of "The Black Island", most of the changes to this third version of the volume were carried out by Hergé's assistant, Bob de Moor. Hergé followed "Land of Black Gold" with "Destination Moon", while "The Adventures of Tintin" itself became a defining part of the Franco-Belgian comics tradition. Critical approaches to the story have been mixed, with differing opinions expressed as to the competing merits of the volume's three versions. The story was adapted for the 1991 animated series "The Adventures of Tintin" by Ellipse and Nelvana.
