This cover features a blue cachet in the lower-left corner depicting a postal horn with a globe inside, along with the United Nations emblem. The cachet text reads 'World Columbian Stamp Expo '92, 25 May 1992, Postal Administration Day' with 'United Nations Postal Administration, Chicago, Illinois' at the bottom. No stamp is affixed to the cover. The envelope appears to be a plain white postal stationery item with no additional markings beyond the cachet.
Mistral
This First Day Cover features a blue cachet in the lower-left corner with a postal horn enclosing a globe and the United Nations emblem, along with text commemorating 'World Columbian Stamp Expo '92' and 'Postal Administration Day' on May 25, 1992. The cover is unstamped and lacks a postmark, indicating it was likely a pre-postmarked philatelic item. The text 'UNITED NATIONS POSTAL ADMINISTRATION CHICAGO, ILLINOIS' is printed below the cachet. The condition appears clean and well-preserved.
(The automatic summaries sometimes misidentify the postmark as part of the cachet artwork.)
