This French commemorative stamp, issued in 1978, marks the 100th anniversary of the École Nationale Supérieure des Télécommunications (ENST), one of France’s leading engineering schools in telecom sciences. The design by Robert Béquet showcases symbolic imagery of telecommunications progress, including antennas, network motifs, and the school’s modern architecture. Printed in a rich monochrome blue, the stamp reflects late-20th-century French design aesthetics and stands out for its clean, technical composition. A desirable thematic item for collectors of science, technology, education, or French commemoratives.
