These Luxembourg semi-postal Caritas stamps commemorate two important national literary figures: poet Michel Lentz (1820–1893) and poet Michel Rodange (1827–1876). Issued in 1947 and 1949 respectively, each stamp bears a denomination of 10f + 5f, with the surcharge supporting charitable social welfare programs. Designed in classic engraved portrait style by Courvoisier S.A., the series reflects Luxembourg’s tradition of honoring cultural heritage through charity stamp issues. Well-preserved examples are appreciated by collectors of European literary themes, semi-postal issues, and Luxembourg philately.
