This very ghostly sign is in Preuilly sur Claise, and I know nothing about it. In fact, I can't really work our what it says except for the name Dubois. The second line is a mystery. A name? A description of the trade carried on within?
I have read the article about the businesses of rue du Puits Berthet in the archeological society magazine "les Cahiers de la Poterne" but this one isn't mentioned.
It may remain a mystery
