Tintin in the Congo is the sequel to Tintin in the Land of the Soviets and the second Tintin book in the series. The book is 62 pages long, and was released in 1931. Although the book has come under criticism for its racist portrayal of the Congolese people and for its portrayal of big game hunting and the mass slaughter of African wildlife, it was quite popular, and was followed a year later by Tintin in America.
