Tintin au pays de l'or noir
On 4 August 1949, the story was suspended part way through its serialisation as Hergé left Belgium for a holiday near to Gland in Switzerland. The magazine used this as a publicity stunt, posting a headline in their next issue declaring "Shocking News: Hergé Has Disappeared!" to encourage speculation as to his whereabouts among the young readership. His co-workers and staff at "Tintin" magazine were increasingly annoyed by unplanned absences such as this, which affected the entire production; his colleague Edgar P. Jacobs sent him letters urging him to return to work. After an absence of twelve weeks, "Land of Black Gold" continued serialisation on 27 October. Following its serialisation, "Land of Black Gold" was collected together and published in a 62-page colour volume by Editions Casterman in 1950.
