Two cancellations are present: a circular pictorial First Day of Issue cancel dated June 26, 1990 from New York, and a special event cancel for the World Columbian Stamp Expo '92 dated May 25, 1992 from Chicago, Illinois featuring a posthorn and globe design.
Mistral
This First Day Cover features a vibrant cachet with stylized '45' numerals in bold black with colorful accents, along with the UN emblem and the word 'Anniversary' in English and French. The two stamps display a rainbow-colored '45' design, with one incorporating the UN emblem and the other featuring a multicolored wave pattern. The cover includes two postmarks: a circular pictorial cancellation from the World Columbian Stamp Expo '92 in Chicago with a globe and post horn design, and an earlier first day of issue postmark from New York dated June 26, 1990. The text on the cover confirms it as an official UN Postal Administration FDC.
(The automatic summaries sometimes misidentify the postmark as part of the cachet artwork.)
