Colombia 1920 SCADTA Airmail, 10c Green on Bluish

Colombia · 1920 · 10c (Centavos)

This stamp features a Farman F.40 biplane in flight over a coastal scene, likely representing the Magdalena River delta. It is part of the first series of semi-official airmail stamps issued by the private airline SCADTA (Sociedad Colombo-Alemana de Transportes Aéreos) for use on its air routes within Colombia.

Issued in 1920, this stamp marks the beginning of regular airmail service in the Americas, operated by SCADTA, a pioneering airline that significantly reduced mail delivery times across Colombia's difficult terrain.
