Chenonceau is inevitably the highlight of any tour of the Loire Valley, certainly the most photogenic, maybe even the coolest castle in the world, the way it straddles the river Cher. The renaissance castle we know today is the third built on the site, completed in the early 16th century.
This poster shows the castle as seen from a distance through fall foliage (richer examples of the color can be found on other specimens). Seeing the castle from a distance was apropos at the time -- the castle was a private home, not necessarily open to the public, and in deteriorating condition.
It was published by the company that was the primary carrier to the Loire Valley, the Orleans Railroad (in French, originally known as Chemins de Fer d'Orleans). The artist, Constant (Leon) Duval, was a prolific posterist for this and other railway companies in the 1910s and 1920s.
