Vienna, a primary criterion for recognizing them as a legitimate postal issue. The Scott Catalog lists them as footnotes without assigned catalog numbers. The UNPA continues to issue stamps, including personalized stamps. It is responsible also for sorting and delivery of mail to the offices under its jurisdiction. Archive sale controversy A recent controversy concerns the 2003 purchase by one organization of the UNPA's entire postal archive, including original artwork and artist's proofs. Apparently this was to raise money for the UNPA, and it may have netted the organization about $2.5 million. However, there have been serious allegations that improper procedures approving the sale were followed under the direction of United Nations Secretary-General Kofi Annan. Also, resale of items at several times their initial values have apparently occurred, thus raising more questions about the entire matter. As of 2006 the issue remains under internal UN investigation. References Further reading Conway, Herbert. 25 years of philatelic highlights. New York: United Nations Postal Administration, 1976, 59p.
