This striking 30 centimes stamp from the Republic of Congo features a detailed botanical illustration of Strophanthus sarmentosus, a tropical plant known for its medicinal properties. Issued in support of the Red Cross, the design elegantly combines science, health, and humanitarian symbolism, with the vivid red cross emblem standing prominently at the lower right. Printed by Enschede, Holland, it reflects the fine engraving and high-quality production typical of the era. A beautiful addition for collectors interested in Red Cross issues, thematic flora, or African philately.
