 Tintin in the Congo was serialised under the French title of Tintin au Congo in Le Petit Vingtième from 5 May 1930 to 11 June 1931 ; it was syndicated to the French Catholic newspaper <unk> <unk> . Drawn in black and white , it followed the same formula employed in Land of the Soviets , remaining " essentially <unk> " according to Michael Farr , and consisting of largely unrelated events that Hergé improvised each week . Hergé later commented on the process of writing these early adventures , stating , " The Petit Vingtième came out on Wednesday evening , and I often didn 't have a clue on Wednesday morning how I was going to get Tintin out of the predicament I had put him in the previous week . " The strip 's visual style was similar to that of Land of the Soviets . In the first instalment of Tintin in the Congo , Hergé featured Quick and <unk> , two young boys from Brussels whom he had recently introduced in another Le Petit Vingtième comic strip , in the crowd of people saying goodbye to Tintin .
