This wandering in old Paris, offered to today's stroller, takes place from 1880 to the 1950's, often tender, sometimes amusing, sometimes delicate or unusual ; a journey through familiar streets, a detour to Luxembourg Garden basin or the charming Quai aux Fleurs, a trip to the 1900 Universal Exhibition and the 1910 flood for the excesses, a look at the crowd on the Grands Boulevards or the intimacy of a private interior during a music session.... An accumulation of fleeting moments that captures the spirit of the City and its inhabitants and the familiar silhouette of the Eiffel Tower watches, in the collections from the very beginning through the photographs of Henri Roger, father of the Agency's founder.
