Anyone heard of Nouvelle Galeries, Paris?

I found Art Nouveau style ceramic kitchen canisters for sale on Etsy from Nouvelle Galeries, Paris. I have not heard anything about them.

I accidentally created this thread before posting photos; photos from the listing are below, with the pottery mark.

Any information or possible age would be appreciated.

 

The mark is for the store of the same name.

They must have ordered them with the store name on it. Here is a the same mold number impressed on a the same form with different decoration. The maker is Longchamp.

And the same design without any maker, yet identified as Longchamp.
