A radio program for philately? Yes, sir, there was in 1949 a "Philatelic Literary Musical Aircast" over DzFM every Friday at 5 p.m. and every Saturday at 6:45 p.m. This slogan cancel was used by the Stamp and Philatelic Division of the Bureau of Posts in Manila. The illustration caricatures an announcer on a microphone. I wonder how long the program lasted and what the content was.
