Nothing remains of the Rue des Écoles in Loos-en-Gohelle but skeletal iron roof trusses, rubble fields, and the stark silhouette of a mining headframe rising from the devastation — this haunting real-photograph card, published by Édition Deschamps of Béthune and visé-stamped in Paris, documents the utter destruction visited on this northern French mining town during the Battle of Loos (September–October 1915), one of the bloodiest British engagements of the entire war, where the British Army deployed poison gas for the first time. The "Visé Paris" certification mark indicates the image passed French military censorship before publication, a standard requirement for war-zone imagery in 1914–1918. The reverse is blank — never posted — retaining the original Carte Postale format with "Correspondance / Adresse" divisions and a printed "M" salutation line. The mining headframe (chevalement) visible at center-right identifies this as the industrial coalfield district of Pas-de-Calais, which sat directly on the Western Front.
