4. Tournai, Ecole Saint-Luc, 1917, large in-folio, chromolithographic frontcover, 8 pp + 40 lithographed plates (4 double plates) designs , plans and groundfloors of church buildings constructions, margins of frontcover frayed and partly cut away, some plates a bit dusty. The cover plates are really the remains of the original porfolio which is thus only partly still present. Rare portfolio with architectural designs published during the First World War, in anticipation of the rebuilding of the ravaged Flemish countryside..
