Issued in 1959, this Caritas semi-postal set from Luxembourg celebrates the heraldic arms of various municipalities, each rendered with elegant simplicity by Courvoisier S.A. under the design of R. Louis. The featured towns include Clervaux (three geese on red), Wiltz (plain red chief on brown field, in two denominations), and Remich (the crowned red lion on blue and white bars). These stamps combined postal value with a charity surcharge in support of Caritas, reflecting the nation’s civic pride and humanitarian spirit. A beloved series among collectors of Luxembourg heraldry and semi-postal issues.
