Chassis 680959 is the first of only four Citroën 15 Six Roadsters ever completed, from a planned 1939 production run of five that was cancelled at the outbreak of war. Never catalogued by the factory, it was originally delivered to Anna Michelin, widow of Pierre Michelin. The sole surviving example retaining factory serial numbers, it carries Citroën Heritage certification and has passed through a distinguished chain of French, American, Dutch, and German owners, undergoing restoration to original factory specification along the way.
