UNDAYPEX

The Chrisquapipex souvenir sheet was overprinted in 1996 by the Asociacion Filatelica de Filipinas for UNDAYPEX, the United Nations Day Philatelic Exhibition held at Manila from October 21 to 26.

This exhibit was held to mark the 21st anniversary of the UN, and a slogan canceller was used to cancel the 6c stamp while a "postmark" was used to cancel the United Nations stamp.
