In 1902, Gabrielle was visiting Freiburg, Germany and sent a card to Monsieur G. Kuentz in St. Lunaire in Brittany, land of beautiful beaches and equally beautiful houses.
Here's another view of Freiburg at about the same time.
The back of the second card is blank, but the back of the first card includes Gabrielle's sweeping script and a few cancellation stamps.
Although I felt like a bit of a stalker, I had to look to see what the Villa des Marguerites looks like. Here it is. This is the side view. The front looks out to the sea. The Villa was built in the 1880s, one of the first villas to be built on the point.
