Colombia SCADTA Consular Overprint Airmail Stamp

Colombia · 1921 · 10c

This stamp is part of the SCADTA Consular Issues, which were regular Colombian postage stamps overprinted for use on the private airmail service operated by the Colombo-German company SCADTA. The overprint, typically in red or black, reads 'SERVICIO POSTAL AEREO DE COLOMBIA' and features the company's emblem, signifying its use for airmail.

SCADTA (Sociedad Colombo-Alemana de Transportes Aéreos) was a pioneering airline founded in 1919, making it the world's second-oldest airline. These consular overprints were sold at Colombian consulates abroad to prepay airmail postage back to Colombia, facilitating international business and communication.
