1 Peso SIAI Marchetti S55

The SIAI-Marchetti S.55 was an Italian flying boat that achieved genuine fame in 1933 when Italo Balbo led a formation of 24 of them on a mass transatlantic crossing from Orbetello to Chicago — a feat of coordinated long-distance aviation that drew enormous international attention. Cuba's decision to commemorate it six decades later fits within a broader series of aviation-themed collector issues the island produced through the 1990s, largely targeting the foreign hard-currency market rather than domestic circulation.
