L'affaire Tournesol - Journal de Tintin

The original story of The Calculus Affair as it appeared in the famous Le Journal de Tintin, originally published between 1954 and 1956. Presenting many differences with the book we've all come to love, especially in the last 20 pages, this version includes a complete restoration of Hergé's original drawings from the well-guarded archives as well as many behind the scene details.

Professor Calculus has invented a machine capable of destroying objects with sound waves. It has already come to the attention of the Bordurian secret services, who will stop at nothing to steal it. When their plans are foiled, they simply kidnap the Professor and take him to Borduria!
