Issued by the United Nations Postal Administration in 1967, this vivid 8-cent stamp commemorates the United Nations Pavilion at Expo 67, held in Montreal, Canada. The design features a striking modernist depiction of the UN Pavilion surrounded by a forest of fluttering flags, set against a radiant spectrum background symbolizing world unity and cooperation. Expo 67 was one of the most celebrated world exhibitions of the 20th century, themed “Man and His World,” and this issue captures the UN’s spirit of international collaboration. A highlight for collectors of UN and Expo-themed philately.
