Not merely labels, these buvards publicitaires were orginally intended to be used as ink blotters as well, and many were collected by school children. That was in the pre-Bic days when all écoliers used a fountain pen and ink in school. (Buvard literally means paper that drinks ink.)
And at a euro or two apiece from a brocante, they could make an inexpensive design statement when framed; perhaps on my kitchen wall?
I bought a half-dozen of these last November and haven't framed them yet. I like the texture of the thick paper. OK, I'm lying. I haven't gotten around to framing them yet.
Inspiration comes from reading Tongue in Cheek's stories of antiques-hunting in France.
