I used to read Tintins quite often in my early teens, and thought I had covered every Tintin published. On researching further, I realized that I had missed out on the first two Tintins, and purchased it in spite of the poor reviews I had read about the adventures - just to complete the collection.
And that's all it has accomplished - helped me complete the works of Tintin. This is an economical way to include the first two Tintin books in one's collection. The binding seems sturdy enough and it seems like the book will last a few years.
But the adventures themselves are a real disappointment. There is little humour in these tales, and the funniest moments in either of these books barely drew a smile from me. What is even worse though, is that neither of the stories seem to have any semblance of a plot. It's just Tintin landing in the USSR and the Congo, and somehow falling into one predicament after another. The attempts by the villains to get rid of Tintin seem much like the plans by Wile E. Coyote to trap the Road-runner - only less inventive. This is aside from the grossly inaccurate depictions of the Soviets and Congolese which have drawn much criticism. But it does convey the views prevalent in much of Europe in the 1930s.
However, I was never bored at any point while reading the stories - they were fast-paced and there is enough action to keep me turning the pages, though with not much excitement.
Overall, I would recommend this 2-in-1 to anybody looking to add these books to their Tintin collection. The stories themselves are not quite enjoyable, especially compared to other Tintin adventures, but they do give some insight into the widely held opinions during the period of their publication.
