This striking Greek welfare issue began life as a 20 lepta social welfare (Πρόνοια) revenue stamp, later surcharged in dark blue with the large “Α.50 ΔΡΑΧΜ.” denomination to meet new postal-fiscal needs during the turbulent WWI period. The design features neo-classical columns and ornate Greek patterns, topped by a prominent blue cross, symbolizing medical and social aid programs. Such surcharged issues are prized for their many varieties, including differing ink strengths and surcharge positions. A well-struck cancellation adds period authenticity, making this an excellent specialty entry for philatelists interested in Greek fiscal-postal hybrids and wartime surcharge history.
