Version 1965

At the request of the british publisher, Hergé decided to redesign the album to bring it more up to the british. The design is certainly successful, but makes this anachronistic album where television recent invention in 1938, became commonplace thing in 1965.

I will recommend editions from 1938 or 1943 when despite a few mistakes (british armed police) we can observe the evolution of the work Hergé.
