This is a 1968 United Nations 13¢ aerogramme (air letter) First Day Cover postmarked at United Nations, New York on May 31, 1968. The imprinted stamp features the UN emblem alongside a stylized airmail motif, with bilingual text in English and French.
Issued during the height of the jet age and expanding international postal cooperation, this aerogramme reflects the UN's role in facilitating global communications through its own postal administration. Aerogrammes were lightweight, foldable airmail sheets popular for economical overseas correspondence in the mid-20th century.
The cover bears a distinctive "First Day of Issue" handstamp showing a mailbox and the UN globe emblem, adding a desirable postal marking to the already attractive light-blue bordered stationery.
A fine addition for collectors of United Nations philately, aerogrammes, or aviation-themed postal history, this FDC displays fresh color and a clear, well-struck postmark.
