During the 1960’s and 1970’s, the comics books, although the fame of be a childish entertainment, has began to use in political and cultural dimension, achieving the status of work of art. In famous French magazine Métal Hurlant, Jean Giraud, aka Moebius, published The Airtight Garage (Le Garage Hermétique). Moebius explored, in his own words, a variety of questions using the Science Fiction theme. His main character, Major Grubert, is a deep space explorer. Beneath that surface, the whole scenario is a colonial one. Grubert, besides he is a spaceship commander, uses typical white-man-in-Africa clothes, including the colonial helmet. He keeps the Airtight Garage as his own reservoir of adventures. Our goal in this presentation is to outline an Airtight Garage’s grammar under the point of a view of colonization. How the memories of French’s colonies are perceived in Moebius’ work? Which concepts can be traced from this story?
