    Le même emballage avec un estampe plus fragile que le votre envoyé vers la Belgique, a été reçu en très bon état avec une satisfaction de l'acheteur; le retard est le dommage de l"estampe a été causé dans votre pays et je ne suis pas responsable. Mais,je suis très désolé à la dommage de cette belle estampe.
