I found a bronze bust of a bohemian girl after E. Villanis, Belgian circa 1900 height 21 inches in my copyright 1975 Sotheby Parke Bernet guide to pricing antiques pg. 32 . Close to yours , necklace with 2 medalions on it. Similar head wrap but this one has no blouse on,looking more to the side than down. sold then for $576.00 may be a lead as to start a search.
