Original WWI Canadian Official press photograph from the Western Front showing Canadian siege gun crews in action firing into Lens. The reverse carries the original typed caption: “Canadian Official Photograph From The Western Front – Canadian siege guns firing into Lens” together with a period Central News Agency / Canadian War Records issue stamp. A powerful wartime image showing Canadian artillery positions, camouflage netting and heavy siege guns in action on the Western Front during the First World War. Excellent piece for collectors of WWI military photography, Canadian Army history, trench warfare and official press photographs. Photos form part of the description.
