Uncommon grouping of three winner's medal proofs designed for the Grenoble 1968 Winter Olympics, for ice hockey, giant slalom, and speed skating. Bronze, 60 mm, 102 gm, by Roger Excoffon, Paris. The front, inscribed, "Xemes Jeux Olympiques D'Hiver, Grenoble 1968," features the Olympic rings; the reverse identifies the sport by text and pictogram: "Hockey Sur Glace," "Slalom Geant," and "Patinage de Vitese." All stamped "Bronze" on the edge. The Grenoble winner's medals were the first to feature a unique design on the reverse for each sport. A highly desirable proof set of pioneering Winter Olympic winner's medals.
