This privately issued souvenir sheet for Chrisquapipex was made by the Asociacion Filatelica de Filipinas.
Chrisquapipex, the Christianization Quatercentennial Philippine International Philatelic Exhibition, was held at Manila from December 6 to 12, 1965.
As noted on the sheet, this was also issued for the inauguration of the AFF as philatelic agent of the United Nations, hence a printed United Nations stamp at left.
Also noted was the fact that it was "printed with the permission of the United Nations Postal Administration."
A 6c stamp of the 1965 Christianization issue is affixed at right while a facsimile of the 70c value of the set is printed (but with different colors from the actual stamp).
