Issued by France in 1975, this commemorative 1.20-franc stamp marks the 100th anniversary of the Senate of the French Republic, established under the Constitutional Laws of 1875. The design presents a finely engraved interior view of the Luxembourg Palace Senate Chamber, rendered with exceptional architectural detail. The curved seating, grand dome, and statues surrounding the chamber capture the solemnity and historical prestige of the upper house of Parliament. Engraved by Decaris, the issue is prized by collectors for its classical linework and strong political-historical significance within French republican history. A notable piece for thematic collections on government, architecture, or national institutions.
