These 1000 drachma notes are dated 1939, that’s 2 years before Greece was occupied by the Axis powers in 1941 during the Second World War. It was the largest denomination at the time and, during the war, Greece suffered terribly from runaway inflation.
The front of the note features a young woman in national dress. The back has a portrait of Athena to the left with an imposing illustration of The Parthenon which even today dominates the Athens skyline. (P110)
