This Greek charity stamp originates from the 1935 definitive issue depicting the ancient sport of bull-leaping (Taurokathapsia). Originally denominated 5 lepta, it was later overprinted in red with a 50 drachmai surcharge to raise funds for the Postal Employees Welfare Fund. The design features athletes engaging in the Minoan bull-leaping ritual, a symbol of strength and agility. Such surcharged issues were common in Greece during the 1930s, often serving dual roles as valid postage and fundraising tools for welfare or social causes. A sought-after piece among collectors of both Greek classics and Red Cross-related philately.
