This Greek 40 lepta definitive stamp is overprinted in blue with the charity inscription “ΥΠΕΡ ΤΩΝ ΘΥΜΑΤΙΚΩΝ Τ.Τ.Τ.”, meaning “For the Tuberculosis Victims, T.T.T.”. Issued as part of a semi-postal surcharge campaign, the stamp features a classical seated figure within an engraved oval, typical of mid-20th-century Greek design. The bold blue 1 drachma surcharge served as a mandatory charitable fee supporting national tuberculosis relief efforts. Such overprint issues are prized for their social-welfare context, numerous variations in type, and their role in Greece’s postal-charitable history. A compelling item for specialists in Greek semi-postals, health fund issues, and surcharge studies.
