This collection of Tintin consists of the tagged story and “Tintin in the Congo”
The first story in the Soviet is in black and white with very simple drawings. In the story everyone is after Tintin, but as far as I can tell it‘s never explained why. It just a series of Tintin getting out of trouble.
The second story takes place in Congo. The illustrations are in color and Tintin looks more like himself. This is also more of a story.
