cover 1789 (28 July) entire letter from Grand Master Emmanuel de Rohan to "Monsieur le Comte de Pondenal, a Agen", redirected to Toulouse, rated "32" and showing a light, though legible, strike of the "DE MALTHE" h.s. (DME) and, on reverse, very fine Arms wafer seal; the letter signed "rohan". Very rare, only a few examples of this handstamp struck alone are recorded. Photo
