a landmark event in Philippine aviation history. The front features the distinctive purple oval "PIONEER FILIPINO OVERSEAS FLIGHT 1936" commemorative cachet and a boxed "VIA ARNAIZ-CALVO FLIGHT" handstamp, alongside the authentic blue ink signatures of legendary aviators Antonio Arnaiz and Juan Calvo. It is franked with United States of America Philippine Islands 10-centavo and 6-centavo stamps, tied by a "LAOAG ILOCOS MAY 28 1936 P.I." dispatch cancellation, and accompanied by a Hong Kong 25-cent stamp. The reverse provides a complete record of the transcontinental route, including a circular "HONG-KONG 29 MY 36" transit mark and a hexagonal "CORREO AEREO 11 JUL 36 MADRID" arrival postmark, making this an exceptional and well-documented piece for aerophilatelic collectors.
