SMORGONY (Belarus): 10 kopeck brown and blue, ample to large margins, tied by pre-philatelic double line "SMORGON 1858/ AUGUST" with "20" added by hand, to small envelope to Warsaw, with arrival marks. The envelope with small imperfections, otherwise fine. A rarity. Just one further No.1-entire recorded from this city and just 11 from Belarus soil. Certificate Buchsbayew (2013)
