Issued in 1984, this Belgian commemorative stamp celebrates the 50th anniversary of Chirojeugd, the largest Catholic youth organization in Belgium, founded in 1934. The modern design by H. B. features two stylized human figures in dark blue and orange, symbolizing friendship, unity, and teamwork. The clean geometric layout and vivid contrast convey the spirit of youth collaboration and community service that defines the Chiro movement. Denominated at 10 francs, this issue reflects Belgium’s recognition of its long-standing youth and social development programs.
