I'm interested in this area but it is a confusing mass of non postage stamp material. Is any one aware of catalogues or resources for identifying and organizing stamps/ cinderellas / from this era? Chris
Fascinating (and challenging) area. Literally thousands of “cinderellas” and other labels
issued by the various political factions etc. of the SCW era.
There are a number of speciality catalogues available. Recommend you start by
“Googling” the topic to identity the various reference sources available.
Am not aware of any “searchable” online reference/catalogue.
A “cornerstone” resource is the Galvez catalogue, which after being out of print
for many years was republished c 1960 by renown SCW philatelist
Ronald Shelley. It is available for loan via the APRL. Content in Spanish.
Images in black/white.
The Edifil specialty Spain/Spain and Colonies catalogue includes some limited SCW content.
