Hi Max,
Little available on-line apart from she studied under Wilhelm von Eiff at the Kunstgewerbeschule, Stuttgart.
Exhibition catalogue has one piece by her illustrated but whether you should consider paying $65?
"Glass of the Avant-Garde: from Vienna Secession to Bauhaus, The Torsten Bröhan Collection from the Museo Nacional de Artes Decorativas, Madrid

Possibly been remaindered.
