Franquin is the leader of an entire generation of authors (mostly at Dupuis, still published in Spirou). The series of books in landscape format allows access to sketches or drawings from an album out of context and thus a priori less worked. This is where we see the real genius of this artist. If we feel the desire (or need) to Marsu Production of making money, it is found that for collectors, this series provides access to difficult to collect drawings. This book is one of the most beautiful of the series (for my taste after Monsters Volume 1 and 2), it is essential to have it, sometimes difficult task: it was published in a small volume.
