A classic U.S. Philippine Islands Official Business stamp, featuring the iconic allegorical Filipina figure beside a carabao, symbolizing agriculture and national strength. Printed in deep green with bold “O.B.” overprint, this issue was designated strictly for government departmental mail. The strong vignette and clean typography make it one of the most recognizable early Philippine definitive designs. Official overprints are highly collectible due to limited postal usage and scarcer survival compared to regular issues. A desirable specialist piece for collectors of U.S. possessions, colonial history, and official stamps.
