APO silver anniversary

For the 1975 set of two stamps marking the 25th anniversary of the APO Philatelic Society, the first day covers were cancelled at three post offices: Manila, Iloilo City and Cebu City.

Shown here is the FDC for the 5-sentimo value cancelled at the Manila Post Office.

The APO Silverpex was held at the Manila Central Post Office from November 24 to 30, 1975.
