Issued by the República del Paraguay on October 24, 1959, this airmail stamp commemorates United Nations Day. It features the map of Paraguay shaded in orange beneath the UN emblem, framed within an architectural arch symbolizing stability and cooperation. The text “Día de las Naciones Unidas 24-X-1959” marks the observance of the UN’s founding anniversary. The denomination, 12.45 guaraníes, indicates its use for airmail (Correo Aéreo).

A fine example of Paraguay’s mid-century commitment to international peace and diplomacy through philately, this issue aligns with other Latin American tributes to the UN during the 1950s.
