1E2 'Servicio Oficial'

The stamps issued on this paper with the 'Servicio Oficial' overprint are all large format:

Here are two used specimens. I find these stamps used between 1938 and 1943. These stamps were used infrequently over a long period of time. This usage is in contrast to the regular issue 1E2 stamp, which was exhausted quickly in 1937.





Here is the back of a pair of the 25c.



Here is a mint block of the 50c1E2-SO. This stamp is very rare used.





Here is a single of the 1p1E2-SO, a rare stamp mint or used.
