cover 1798 (26 October) entire letter with printed French heading of the 15th Division Militaire written at Dieppe and addressed to a Captain at Rouen, showing a superb strike of the "DON. I. PORT-PAYE/ARM.D'ANGLETERRE" in red at top-right; a very fine and clean item. Probably the finest known example of this extremely rare marking and without doubt of exhibition quality. Photo
