Issued under United States administration of the Philippines, this 1936 commemorative honors Manuel L. Quezon, first President of the Philippine Commonwealth, marking the 1st anniversary of the Commonwealth (Nov. 15, 1935). The finely engraved design features Quezon’s portrait flanked by allegorical figures symbolizing liberty and progress, with the banner “Commonwealth of the Philippines.” Printed in green and denominated 6 centavos, this stamp reflects a pivotal transitional era leading toward Philippine independence. A historically significant issue sought after by collectors of U.S. possessions and Philippine political history.
