| A young boy, dressed in a French military-style cap and uniform jacket, sits on the ground, engrossed in a book. He is holding a lit pipe in his mouth. The card is titled 'La Théorie' (The Theory) in French and English. A handwritten Christmas and New Year greeting is present. The back reveals it was sent by a French soldier in Fontainebleau in December 1917 during World War I. |
