This 20-cent stamp from Rwanda, issued in 1982, honors Mgr. Joseph Cardijn, founder of the Young Christian Workers (JOC) movement. The design depicts two children engaged in cooperative farm work, echoing Cardijn’s lifelong mission of social upliftment, youth empowerment, and dignity through labor. Printed by Cartor and illustrated by L. Dobon, the stamp combines warm pastoral imagery with the JOC emblem, making it a meaningful thematic item for collectors of social reform, education, and humanitarian themes. A fine addition to any Rwanda or social-movement collection.
