Issued by Austria in 1985, this 4 schilling commemorative stamp marks the 25th anniversary of the European Free Trade Association (EFTA). The design by A. Pilch features a modern emblem with the inscription “25 Jahre EFTA” surrounded by the flags of the member nations—Austria, Finland, Iceland, Liechtenstein, Norway, Portugal, Sweden, and Switzerland. The caduceus motif symbolizes trade and cooperation, reflecting the organization’s goal of promoting free trade and economic growth among European nations outside the EEC. A bold green background enhances the multicolored flags and emblematic design.
