Issued by the République Française in 1966, this 0.60-franc commemorative highlights the 19th International Railway Congress held in Paris. The design powerfully combines railway tracks with a stylized globe, symbolizing global rail connectivity, while the Eiffel Tower marks the host city. Rendered in rich red-brown and blue tones, the stamp reflects France’s leadership in international rail development during the mid-20th century. A well-engraved issue sought after by collectors of transport, engineering conferences, and French commemoratives.
