274th - 283th Corinphila Auction - Day 4

1882: 15 st. purple and pale mauve making the 15 st. rate on a return receipt for a registered letter from PIRDORP to Sofia. The stamp is tied by black bilingual Sofia cds. A crease affecting the stamp and some minor weaknesses to the paper do not detract from this rarity. The bilingual cachet PIRDORP is very rarely found on items bearing the stamps of the Lion design. Opinion Penev (2021).
