The Waite-Saville presses show 3 types of margins for the multicoloured stamps!

But are they really Waite-Saville???

Buenos días Rein.
is it possible that the margins were printing on a GOEBEL to disable the paper to prevent it was used to print counterfeits?

In 1916 in Mexico the Provisional Government did "overprint" a lot of stamps -whether they had earlier overprints or not - with a scroll containng the text "G.P.de M." i.e. "Gobierno Provisional de Mexico".

The handbooks and catalogues - Mexican philatelists in particular - claim the overprints to be in typography!

When you pay a good look at them - magnification of 10 times or more - you will notice that it doesn't look like typography at all, it rather reminds you of recess printing. You may even feel it by touchting ther surface, the ink lies clearly on top of the paper surface.

Knowing the Mexican State Printers had die-stamping equipment from the French Voirin or the English Waite&Saville manufacturers probably as early as 1911, it s most likely these machines were also used to apply the "overprints" to a bulk of stamps still available.

These overprints clearly are recess engraved or intaglio, and the catalogs and handbooks I have seen state correctly they are "engraved" or don't state the method of printing. I have not seen any say they were printed by typography, but some might have:

Carlos Fernandez Teran, Catalogo Filatelico Timbres Mexicanos 1856-2008 (the corbata or "bow tie" overprint is "grabado en acero" = engraved in steel p. 81; "engraved overprint"; the barril or "barrel" overprint is "grabada" or "engraved" p. 89)

Nicholas Follasnsbee, The Stamps of the Mexican Revolution 1913-1916 (1996) ("corbata" was an "engraved overprint" p. 170; and the "barril" was "engraved" p. 184.

Guillermo Celis Cano, Sellos Postales de Mexico (1974) just calls these "sobrecargas" or "overprints" but does not state their method of printing. Same with Scott and Minkus.

Very interesting all your studies about worldwide philately. Congratulations Rein.

Back to Mexico circa 1917:

recess:




screenless photogravure:




to be continued ....

Although Ten Years After [Alvin Lee ] when one looks at the value tablets there are remarkable differences that have not been mentioned before in Mexican philatelic literature!
