Greece - Pair Of Unidentified Stamps

I have finally managed sorting through all of my Dad's stamps from Greece and identified all except for these 2. Can someone help with a catalogue number for these?

Private issue (cinderellas) from 1917, showing the political leader Eleftherios Venizelos.

Hi, let me add more information to vayolene description. These were issued as propaganda labels in 1916-7 for the State of Thessaloniki also known as the Provisional Government of National Defence, a parallel administration, set up in the city of Thessaloniki by former Prime Minister Eleftherios Venizelos and his supporters during World War I, in opposition and rivalry to the official royal government in Athens.

There are four more labels in this set show Venizelos with Pavlos Kountouriotis and Panagiotis Danglis, called "The Triumvirate", the leaders of the State of Thessaloniki.
