 Hergé characterised Wallez 's instructions in a sarcastic manner , saying Wallez referred to the Congo as " our beautiful colony which has great need of us , <unk> , <unk> " . He already had some experience in illustrating Congolese scenes ; three years previously , Hergé had provided two illustrations for the newspaper that appeared in an article celebrating the fiftieth anniversary of Henry Morton Stanley 's expedition to the Congo . In one of these , Hergé depicted a native Congolese <unk> before a European , a scene that he repeated in Tintin in the Congo .
