Heinrich Köhler 384 Auction – Day 1 Single Lots: Europe and Colonies, Kingdom of Lombardy–Venetia – The "P.G." Collection

1885 (September 17), postal card franked with two 10pa green, perforated 11.5, Type I overprints, one each in black and blue aniline ink, each cancelled with crisp Tirnovo Seimen c.d.s. in green, to Sofia, with c.d.s. arrival backstamp (Sep 20), a lovely and scarce franking, handstamped Buhler.
Note: This card was franked at a total of 20pa, the prevailing rate for postcards sent abroad. However, following the revolution earlier in September, Bulgaria was  covered by the 10pa inland rate, this card thus being overpaid by 10pa.
