Here is the mark. On closer study I think it says "BDS" in the "peace sign" area. I apologize if my earlier post misled you.
As I mentioned above, because of other research I've done, I believe this mark is not the maker, but rather an American importer's stamp, possibly a department store. Speculation on other sites indicates that these vases may have been made specifically for export, an idea borne out by the fact that the stamp says "France" in English. The origin of the 3-letter acronym has thus far been impossible to trace conclusively; however, the U.S. department store or importer theory seems logical.
I believe the style, color, and aging is consistent with something made ca. 1930.
I've found pictures on the internet of one of these vases in green - like mine - and one in brown, from the online store that won't write me back. Both lean towards Muller Freres as the maker. I just wanted to find out if that made sense to any of you, or if you had a different - and better - idea on attritubution.
In any case, I've never seen one with these metal "cradles," and hoped that one of you would have an idea on value, especially for the pair.
