It was a pleasure meeting you in Buenos Aires -- thanks for making my first time to South America a memorable experience!

I passed through Barcelona-El Prat Airport in Barcelona, Spain in 2026, and I got to mint this pretty POAP! BCN is named for the nearby town of El Prat de Llobregat, and its super close to Barcelona. It's known for having excellent Mediterranean views during landing. This POAP was minted in 2026 as part of a campaign to offer precious digital collectibles to travellers around the world.

I passed through Adolfo Suárez Madrid–Barajas Airport in Madrid, Spain and I got to mint this pretty POAP! MAD Terminal 4 (T4), opened in 2006, is one of the largest airport terminals in the world (about 760,000 m² including its satellite), and features a driverless automated people mover to connect with the satellite building. This POAP was minted in Q4, 2025 as part of a campaign to offer precious collectibles to travellers at 18 airports around the world.

I passed through Ministro Pistarini International Airport in Buenos Aires, Argentina and I got to mint this pretty POAP! Ezeiza is where Argentina’s first international flight departed in 1949—it was inaugurated by President Juan Perón and Eva Perón. This POAP was minted in Q4, 2025 as part of a campaign to offer precious collectibles to travelers at 18 airports around the world.
