This Greek Anti-Tuberculosis charity tax stamp (TT issue) features a classical allegorical design showing a seated female figure feeding a serpent beneath a stylized tree, symbolizing healing and medical care. Originally issued with a lower denomination, this example carries a bold “50” surcharge overprint, reflecting a revised postal tax rate used for tuberculosis relief funding. Such overprinted charity issues are collected both for their social-history significance and for the variety of surcharge types and printings. Clean impressions and well-centered overprints are especially desirable among specialists of Greek fiscal and semi-postal material. A classic mid-20th-century public-health fundraising stamp from Greece.
