Auction 186-190

20 pa. black on green, fine used examples (2) on front and back of registered cover to Tophane, the adhesives each tied by dotted handstamps in black with 23 AU 66 / S / GALATA oval datestamp below and bilingual CHARGÉ at top of cover. Five red wax seals on reverse, the letter endorsed 'Poids 3' and thus probably accompanying a gift to the addressee: Hassan Pasha of the Imperial Artillery. Rare and most appealing cover, probably the most attractive of the handful of registered covers recorded.
