Issued by Luxembourg in 1973, this Caritas semi-postal set features five finely detailed medieval religious sculptures. Each stamp carries a surcharge to support charitable causes, reflecting Luxembourg’s long-standing Caritas tradition. The designs depict biblical and devotional scenes rendered in rich, solid background colours that enhance the carved figures. Printed by Courvoisier S.A., the set is admired for its artistic depth and textured presentation. A classic 1970s European charity issue, highly collectible for thematic collectors of religion, art, and semi-postals.
