Samivel embodies a universal image of the mountain through the variety of his work, while Rochette is considered the current master of the graphic mountain novel. What they have in common is a passion for mountaineering and the purity of high altitude lines. A tribute to Samivel, who passed away 30 years ago, and a warm festival welcome to Jean-Marc Rochette. He will be joined by two talented authors who have published innovative works in recent weeks.
