This car was a project of Mr. Voisin for the Poste Française and was known as "Monoplace du Facteur". Incidentally, isn't a Biscuter as that name was applied by Autonacional in Spain for the Biscooter Voisin made near Barcelona, as "u" in Spanish sounds as "oo" in English, anyway it wasn't a Biscooter either as was single seat or Monoplace...
