Issued by Switzerland (Helvetia) in 1955, this 5 centimes commemorative stamp celebrates the National Philatelic Exhibition held in Lausanne. The design beautifully features the iconic Lausanne Cathedral alongside a ceremonial Swiss horn adorned with the national cross emblem. Printed by Courvoisier S.A., the stamp reflects the fine engraving quality Swiss issues are known for. The warm brown background enhances the architectural detailing and symbolic motif. A classic mid-20th-century Swiss exhibition issue, it is highly collectible for both thematic (Philately, Architecture, Switzerland) and exhibition collections.
