This 10-centime Swiss commemorative stamp, issued in 1967, celebrates the 50th Anniversary of the Swiss Week (Schweizer Woche, 1917–1967). Designed by H. R. Lauterburg and printed by Courvoisier S.A., it features a bold, modern composition combining the Swiss flag and a metal gear, symbolizing the union of Swiss identity and industrial progress. The tri-lingual inscription (“Schweizer Woche / Semaine Suisse / Settimana Svizzera”) reflects Switzerland’s cultural diversity. The clean geometric layout and vibrant color scheme make it an excellent example of mid-20th-century Swiss design.
