Issued by France in 1975 for the international philatelic exhibition ARPHILA ’75 in Paris, this striking 1.00 franc commemorative features a bold modernist design by Beat Knoblauch, depicting a stylized close-up of a human eye rendered in dotted halftone patterns of purple and orange. The composition is a classic example of 1970s French graphic philately, emphasizing artistic flair over traditional motifs. Printed by photogravure, it remains a favorite among thematic collectors of art, exhibitions, and philatelic events. A visually iconic issue representing the creative spirit of French postal design during the decade.
