Le Manitoba ne répond plus (Les Aventures de Jo, Zette et Jocko #4)

Hergé, creator of the world-wide sensation "Tintin", began this new series in 1935, about an adventuring pair of siblings, and their pet monkey. Although he would enjoy writing younger characters, with more vivid imaginations, the artist often found himself frustrated by the fact that - compared to his famous boy reporter - Jo and Zette had less freedom to travel, due to their being children.
