There might have been other products or services advertised on this wall but nowadays it is the names of two alcoholic drinks that stand out.
On the left is a ghost sign for Kronenbourg. Some information about this beer was posted earlier: see Kronenbourg, Saint-André-de-Cubzac.
And on the right is a better-preserved sign for the Noilly Prat. To find out more about this particular brand of vermouth, check this earlier post: Vermouth Noilly Prat, Saint-André-de-Cubzac
Part of another advert can be seen on the left of the picture below but I haven't managed to identify it.
Location: former RN10, Montlieu-la-Garde, Charente-Maritime
