America UPAEP. Architecture - Skyscraper Skyline Madrid - Mint - Sheetlets

Since 1989, each one of the postal operators belonging to The Postal Union of the Americas, Spain and Portugal (PUASP) has been issuing a stamp based on a common theme annually. This year the chosen theme is architecture. Correos has chosen to issue a miniature sheet consisting of six stamps that are dedicated to the skyscrapers that make up Madrid’s most current skyline, the cut-out image of the Spanish capital’s outline in the sky, which is defined by towers and skyscrapers that can be observed from each and every corner of the city.
