I have a pair of lovely 8-1/2" vases, cobalt blue cut to clear. They each have a circular silver foil label which reads: "Au Claire / 10 Vendome Place / Paris France". is Au Claire a glass company, or are they a retailer/importer? I have not been able to find any information about them. I have had the vases for many years, and love them! They are similar to vases in my collection of Bohemian glass, but somehow different. Any thoughts?
Thanks
