This modestly sized publication presents a detailed street‑level plan of Saint‑Germain‑en‑Laye, a historic commune just west of Paris. Produced by Editions L. Petit in 1977, the map offers a clear layout of the town’s streets, public squares, and notable landmarks, making it a handy reference for visitors, residents, and local historians. Printed on durable paper, the work combines practical navigation with a touch of mid‑20th‑century French cartographic style, serving both as a functional guide and a collectible snapshot of the town’s urban fabric at that time.
