FINE AND COLORFUL EXAMPLE OF THE PHANTOM RATE TO FRANCE SHOWING A VERY EARLY APPLICATION OF THE 6-CENT CREDIT TO ENGLAND.
Effective July 1, 1870, the new Anglo-French postal convention reduced the rate between Great Britain and France to 3p per 10 grams, which in turn reduced the Phantom Rate from 12c to 10c (with a corresponding reduction in credit to GB from 8c to 6c). The 15c stamp is a typical overpayment of the 10c Phantom Rate. The cover was carried on the Cunarder Aleppo on its first voyage, departing New York on July 7, 1870.
Ex Hubbard, Coulter and Eubanks. With 2006 P.F. certificate.
