20l. sky-blue (pos.144), uneven control numbers with "0" lower (Kound. 47.8), used. 1871 first setting as this stamp bears the same "2" with 1870 20 lepta stamps. Good-large margins all around but upper right corner crease. Still fine for this since it is the first time we found uneven control figures with "0" lower for 1871/72 stamps. Interesting is that this error exists in pos.144 in 1871/76 20 lepta stamps also. (Hellas 35a).
