"The postal museum is hidden at the third floor of the building of the Security Inspection Services Division and Postal Police Force that any Manileño would scratch his head in wonder at not knowing that it exists and is in fact the oldest museum in southeast Asia.

It was organized in 1992 to enable the public to view the country’s rich repository of stamps and items used by the post office through the years including: Old mail boxes, typewriters, awards, paintings, stamps, philatelic magazines, as well as books and catalogues."
