Lote 204

✉ FRANCIA. 1870 (5 Oct.). PARIS to MARGATE (Great Britain). BALLOON "LE NOM DENOMME Nº 1" and "LE JEAN BART Nº 1". Envelope with full contents initially put on "Le Nom Denomme nº 1", then recoreved and flow out on the "Jean Bart nº 2". Arrival on reverse (19 Oct.). The contents of this letter have benefited from detailed research, in revealing how undercover mail was transmitted out of Paris. Usual faults.
