This young comic book author and illustrator made his Hermes debut with Wow!, a double-faced scarf that follows the adventures of Marie, The Hermes Woman. Bienvenu also directed a series of animated shorts for Hermes featuring Marie's journey. Wow! was paired with La Premier Chant in the muffler format, and adapted to the Arceau timepiece. Marie's space horse's herdmates reappear in Space Derby, Rendez-Vous Galant, and the reinvention of Robert Dallet's classic Mustangs in 2023.
