HIKER275 - I am afraid there is no URL of the
Institut de Gravure - PARIS, which was a private company according to the following passage in French "
... Il (Monsiuer L. Demoulin, directeur de l'Atelier du timbre-poste) avait comme allié (non désintéressé) l'Institut de gravure, imprimerie privée qui éditait elle aussi des vignettes commémoratives mais en taille-douce (10) ..." appearing on
http://www.timbresmag.com/2016/01/2...e-cheffer-i/ .
Back in 2016, while looking for information on this printer, I consulted
http://www.philateca.com/printer/In...t+de+Gravure , which said:
Printer: Institut de Gravure = Institut de Gravure et d'Impression de Papiers-Valeurs, Paris. Alias: H.V. Paris = Inst de Grav = Inst de Grav. = Inst. de Grav. = Inst. de Grav. Paris = Inst. de Gravure = Institut de Gravure - Paris = Institut de Gravure ParisH.V. Paris (= Hélio-Vaugirard Paris) being an alias of
Institut de Gravure was surprising because
heliogravure = photogravure or gravure is a photo-mechanical process, different from hand engraving.
A search for Hélio-Vaugirard Paris lead to
https://de.wikipedia.org/wiki/Druck...io-Vaugirard where no mention of the
Institut de Gravure, Paris was made.
Thinking that no info on the postage stamp printer
L'Institut de Gravure, Paris was available on the internet, I searched my earlier w/w collection of used stamps for those carrying its imprint besides identifying such stamps in my
Lipsia 1954/55 Europa as well as my 1971 edition of the
Stanley Gibbons Stamps of the World catalogues (where the photos of them were so good that I was able to discern the imprints on the stamps in question). In this way, I was able to compile a list of their stamps.
From the list below, you can see that the company started its stamp printing activities in the last third of the 1920s, expanded in the 1930s and 1940s printing stamps for French colonies mainly, and wound up printing stamps for South American countries from 1948 till 1955. Later on, the company apears to have gone out of stamp printing business.
