St. Jean de Bretagne Ceramics Handpainted

I purchased this at an auction. It is a set with a large bowl with lid, a large plate, a slightly smaller plate, two even smaller plates, two 3 little handled cups and a small bowl. I'm not sure what this is supposed to be used for, I bought it because I loved the pattern. I then discovered that everything is completely hand painted. I've found a couple websites (in French) that helped a little, but I really am curious to know the real value of these pieces. BTW, one of the little handled cups is glued back together from an old break (not done by myself). I'm also including the link to the site I found with additional information.
