Fragment of the folded cover of a letter sent to Saint Mesmin (FRANCE) with the rare mark "NUEVAS MENSAGERIAS NACIONALES DE MERLINO Y CAMPANELLA" (GJ.MSJ126), perfectly applied in green. It also bears a French due mark "30", very fine quality, rare. An entire letter of this stagecoach mail sent to France would have a market value of between US$2000 and 3000, good opportunity! (Image)
