We met a gentleman a years ago that traveled throughout Europe buying out old glass jewelry factories and remnants of family-ran businesses in the late 80's and he would purchase EVERYTHING from them. He would crawl through dirty basements and climb into dusty attics to find all of these wonderful treasures. He retired about 18 years ago and since then all of this jewelry has been stored in his warehouse.
