This Ecuadorian stamp, originally issued at 20 centavos, features the historic Casa de Correos (Central Post Office) building, a landmark of national postal heritage. Printed in a rich brown tone, the design highlights ornate framing around the grand architecture. The bold black "POSTAL" overprint distinguishes its use as an official postal issue, making it a specialized variety sought after by philatelists. Such overprints were often applied to revalidate or reassign stock for postal purposes. A fine example of Ecuador’s early 20th-century postal history, this issue remains a desirable collectible for both thematic and historical collections.
