Centenary of the International Telecommunication Union

This commemorative airmail (Poste Aérienne) issue illustrates the rapid evolution of global telecommunications engineering over a century, juxtaposing historical land-based systems with modern space infrastructure. The complex layout features an early manual telegraph straight-key transmitter connected to overhead wire lines on wooden telegraph poles, looking upward toward a synchronized orbital communications satellite operating amidst a field of stars. The design is anchored by the circular centenary emblem of the International Telecommunication Union (UIT), marking its trajectory from 1865 to 1965. Historically, this release captures a critical mid-century period when the Comoros was being integrated into modern global communication networks, shifting from isolated oceanic cables directly to international shortwave radio routing and global satellite telemetry.
