Comic book by Herge.
It appeared between June 1930 and June 1931 in Le Petit Vingtième (the children's supplement to the Belgian newspaper Le Vingtième Siècle). The story was published as an album in 1931, in black and white form. It was re-drawn in 1946, with additional changes in 1975.
It has provoked controversy, particularly in modern times, with complaints from people who feel the depiction of Africans is racist, and from animal rights groups who feel Tintin engages in cruel behaviour. Hergé later said that he was influenced by the naïve, colonialist views of the time. At the time he was much influenced by his employer, Wallez, who decided that the Belgian youth needed to know more about the values of colonialism.[1]
Hergé was very young and only in the beginnings of his career when he drew this volume, later describing it as "the sin of his youth." Hergé himself did not intend to be offensive or malicious towards the people of the Congo. (Source wiki)
