The 1E1 issue of the 25c 'Servicio Oficial'

This stamp is consistent with the clear impression of the 1E1 printing and the 1E1 watermark, with a notable exception: these stamps were used in 1939 and 1940 and the paper is bright white. The 1E1 paper is cream. My educated guess is that a different pulp was used.

Here is a scan of the watermark.

Here is a specimen postmarked in May 1939.

This specimen has gaps in the overprint.

This specimen has the 2 of 25 deformed. To date, I have not confirmed this flaw as a repeatable plate variety.
