Issued in 1963 as part of Luxembourg’s annual Caritas semi-postal series, this beautifully engraved 10F + 5.90F stamp features St. Thibaut (Theobald), celebrated as the patron of the seven traditional trades. Printed by Courvoisier S.A., the design shows the saint within a floral oval frame topped by a crown and guild emblems, symbolising the strong craft heritage of Luxembourg. The surcharge supported charitable causes, enhancing the appeal of this issue to philatelists specializing in semi-postals and thematic religious stamps. Its fine detailing and soft pastel background make it a notable piece in mid-20th-century Luxembourg philately.
