United Nations Offices in New York

The United Nations offices in New York have postal services for its delegates and visitors. Their stamps denominated in US currency are only valid when mailed from the UN complex, with mail handled via the United States post office/postal service. Still. for the public, mailing facilities are only open for a few hours a month, very strange for someone who calls themselves a postal administration.

There are joint issues of all three major offices.

 * In 1951, a definitive series was issued with "United Nations" in up to five languages. An airmail series was issued the same year.
 * By 1979, only "UNITED NATONS" was inscribed on New York issues.
 * 1980 saw the first of the flags of member nations series
 * Beginning in 1984, year dates were regularly added to stamps.
 * In the 2010s, at least two issues lacked any identifier as to the origin of the stamps; see below. Not very UPU-compliant, so perhaps not real postage stamps?
