Entire letter dated Asunción 5/MAY/1864, sent to Buenos Aires by 'Ygurey', with the black oval mark 'ADMon GRAL - DE CORREOS - DE LA R. DEL P.', VF quality, entire letters of Paraguay from this period are very rare, and they help verify the usage dates of cancels and their colors! (Image)

4 Postal stationeries with additional franking + 1 PC sent to Argentina between 1892 and 1936, very nice and interesting! (Image)
