1917 Greece 20 Lepta Revenue Stamp with KP Overprint

Greece · 1917 · 20 lepta

The stamp features a portrait, likely of a monarch, within an oval frame, with an overprint 'Κ.Π. 20 ΛΕΠΤΑ'. The base stamp is a 1913 issue.

Issued in 1917 as a social/charity tax stamp, it was an overprint on an earlier 1913 occupation revenue stamp. This particular example was postally used in 1918, after the official withdrawal of these 'KP' stamps, highlighting its unusual later usage.
