 At Casterman 's prompting , Tintin in the Congo was subsequently fully re @-@ drawn , and the new version was published in 1946 . As a part of this modification , Hergé cut the page length from 110 plates to the standard 62 pages , as suggested by the publisher Casterman . He also made several changes to the story , cutting many of the references to Belgium and colonial rule . For example , in the scene where Tintin teaches Congolese school children about geography , he states in the 1930 – 31 version , " My dear friends , today I 'm going to talk to you about your country : Belgium ! " whereas in the 1946 version , he instead gives them a mathematics lesson . Hergé also changed the character of Jimmy <unk> , the owner of the leopard that attacks Tintin , from a black manager of the Great American Circus into a white " supplier of the biggest zoos in Europe .
