Issued by Luxembourg, this 2.50 Franc stamp commemorates the nation’s pavilion at the 1958 Exposition Universelle de Bruxelles (Brussels World’s Fair). Designed by architect Lex Weyer, the modernist structure is depicted in striking blue and white tones against a vivid red background, symbolizing innovation and national pride. The stamp celebrates Luxembourg’s participation in a major post-war international exhibition that showcased progress in architecture, technology, and culture. Printed by Courvoisier S.A., it remains a valued piece for collectors of world’s fair and architectural themes.
