I am on a quest of a kind for a Louis Vuitton Epi Serviette Ambassadeur or Serviette Conseiller briefcase and have two questions that maybe a knowledgeable person can answer… 1. Is there an online or print resource that describes in more than trivial detail the various Louis Vuitton Serviette briefcases (such as Serviette Conseiller, Serviette Ambassadeur, Serviette Fermoir, Serviette Moskova, Serviette Kourad etc.) such as model numbers, years of production etc. 2. Is there a store in New York City that specializes in vintage/used Louis Vuitton briefcases? Any assistance or knowledge is most appreciated, thank you.
