10l. orange on blue (pos.12), widely spaced control numbers (Kound. 30.6) canc. "110" (=ΑΡΓΟΣΤΟΛΙΟΝ (ΚΕΦΑΛΛ.)". Very rare error as it exists only on position 12 of the orange on blue 10 lepta setting. Three very large margins but bottom margin very narrow. Still fine-very fine for this. (Hellas 18dNk).
