In 1931 and 1932, the 120 black-and-white pages were published for the first time in serial form in the children’s supplement of the Belgian daily newspaper Le XXe Siècle before being published as a book in 1932 by Éditions du Petit “Vingtième”. In 1942, Hergé began redesigning this story by condensing it into 62 colour pages for publication in 1946. Eighty-nine years after its creation, Moulinsart has carried out the colorization of the original version following the colouring of the original versions of Tintin in the Land of the Soviets and Tintin in the Congo. The colorization is deployed around the original black flat tints. It is an adaptation of the first complete version. The colourists favoured respect for the power of black and white. It is in this sense that we speak of “colorization”.
