This striking Greek charity issue begins as a 40 lepta “Seated Hermes” definitive, later overprinted in vivid red for a special welfare surcharge. The overprint reads “ΥΠΕΡ ΤΩΝ ΣΥΜΜΑΤΙΚΩΝ Π.Τ.Τ.” (“For the Allied Postal & Telegraph Fund”) and raises the postal value to 2 drachmai. The bold red cross and diagonal script make this one of the most visually distinctive Greek overprints of the era. Such charity surcharges were produced in limited numbers and are sought for their historical context tied to wartime relief efforts. A strong, clean impression and crisp overprint enhance desirability for specialized overprint collectors.
