Issued by Belgium in 1974, this striking semi-postal stamp (10f + 5f) features a modern traffic light motif symbolizing the “green light” for humanitarian action. The red cross emblem prominently appears within the upper lens, merging contemporary design with the universal symbol of aid. The surcharge of 5 francs supported the Belgian Red Cross, reflecting the nation’s ongoing commitment to charitable causes through philately. Its vivid purple background and minimalist design make it a favorite among thematic collectors of Red Cross and modern graphic issues.
