F FORGERY: 20c. blue Marseille Postal Forgery, very good to large margins and affixed to 1870 (29 Dec.) "Caire Frères" entire letter from Marseille to Roquevaire (30.12 arrival), tied by "2240" gros chiffres and with despatch c.d.s. adjacent; light horizontal filing crease crosses the lower margin of the adhesive, otherwise a very fine example of this elusive rarity. Cotin Certificate (1964). C. F46, FF. 29,500. Photo
