This albumen print by Eugène Atget documents the historic Saint Denis postal relay station at Ecouen, known as the Hôtel du Grand Cerf, capturing the architectural vernacular of early modern France with the photographer's characteristic attention to structural detail and urban topography. The negative numbering and pencil annotations on the verso reflect Atget's systematic cataloging of his extensive archive of Parisian and provincial buildings. As an albumen print, the work exemplifies the photographic medium's capacity for fine tonal gradation, a quality central to Atget's documentary project undertaken primarily between the 1890s and 1920s.
