i'm happy that you also appreciated those plates and the period...
the Museum of Thervuren in Bruxelles has, in his library, many other platetes depicting scenes, above all military, from the same illustrator...and something else could be find in Musée de l'Armée and another Museum..in think in another city..which is devoted to the Belgian African Congo...in this period , in Thervuren, there is also an exhibition on Congolose troops participation in WW1 (German East Africa and Kamerun)..i suppose it should be worth a look..probably above all for artefacts and picts..including unpublished uniform plates cards from the same James Thiriar ...the only danger could only be, as i easily imagine, the pletoria of "politically correct captions which, in those days, cannot be avoided to show to the masses anything colonial and military...
