Desmadryl 5 c. chestnut brown, nice deep colour, just touched that central left, otherwise large margins, tied by target to letter sheet, dated "26.Janvier 1854", with adjacent straight line handstamps "SERENA" and paquebot marking "CABOTAJE", and endorsed "Vapor", to Valparaiso. Very fine and most unusual; supposed to be the earliest recorded use of the 5 c. chestnut-brown and very rare use of the pre-philatelic "CABOTAJE". Certificate Moorhouse (2007) (Scott 3b)
