From a high vantage above the Rhône's outflow into Lac Léman, this sweeping collotype panorama takes in the Île Jean-Jacques Rousseau — its dark canopy of poplars and plane trees rising like a natural fortress from the water — flanked by the elegant stone quays of Geneva, a horse-tram crossing the Pont des Bergues at right and steamboats moored in the harbour beyond, the distant shore of the lake dissolving into a luminous haze; it is Belle Époque Geneva at its most patrician, a city of diplomats, watchmakers, and the philosopher's ghost, frozen in silver gelatin by the lens of G.L.M. The undivided Swiss carte postale back, printed for all three national languages, anchors the card firmly in the pre-1904 golden age of European postcard collecting.
