5 volumes from 1924 to 1928, 1 per year intended to be grouped in a brown slipcase specially designed for this. Our edition has lost this one which is replaced by another which is green and later but perfectly adapted to these 5 books.The texts are mainly by the authors Montorgueil and Louis Forest and the numerous illustrations by illustrators famous at the time, among which in the 5th volume, the very famous and woderful drawings of Charles Martin. All, with a lot of humor and documentation at the same time.
