Issued by Costa Rica, this 15 céntimos airmail stamp highlights the country’s vital sugar industry (azúcar). The design features a sugarcane field and processing factory with smoking chimneys, symbolizing national industrial progress. Printed in Vienna by Imprenta Nacional de Austria, it forms part of the Industrias Nacionales (National Industries) series celebrating key sectors of Costa Rica’s economy. The orange frame and grey central vignette create a balanced, elegant composition typical of 1950s–60s industrial airmail issues.
