From war-torn Warsaw in August 1917 — while the city was under German occupation during the First World War — an ardent correspondent named (from the closing) possibly "Georg" penned a passionate letter in flowing German Kurrent script across every available surface of this colorful Polish art postcard, addressing his "mein einzig Juwel!" (my only jewel). The front reproduces a luminous painting by Wincenty Wodzinowski (1866–1940), one of Poland's most celebrated genre painters, showing a peasant girl in folk costume seated at a sunlit window, her embroidery in her lap, gazing outward with a dreamy smile — the work titled Przy oknie (By the Window), dated 1913 on the canvas. Published by Nakład J. Czerneckiego w Wieliczce, a Galician publisher, and numbered 32 in their art series, this card is a remarkable convergence of Polish cultural pride, wartime occupation, and intense personal correspondence.
