This Brazilian airmail stamp, printed in a deep reddish-brown tone, honors Alberto Santos-Dumont, celebrated as the “Pai da Aviação” (Father of Aviation). The design features his pioneering 14-bis aircraft, the world’s first heavier-than-air machine to take off, fly, and land entirely under its own power in 1906. The left vertical inscription “BRASIL” identifies the issuing country, while “CORREIO AÉREO” denotes its airmail purpose. The denomination of Cr$ 11,50 (Brazilian cruzeiros) reflects mid-20th-century postal rates for air correspondence.

This issue commemorates Brazil’s pride in Santos-Dumont’s contributions to early aviation and his place among global aviation pioneers.
