Ths is a very nice sterlng brooch by,Frances Holmes Boothby. She has become recognized as an important part of the American Modernist jewelry movement, and her work was featured at two important exhibitions of contemporary jewelry at The Walker Art Center in Minneapolis in 1948 and 1955. Boothby signed all her pieces with a lowercase "fhb" and when she was working in silver the word "STERLING" all in uppercase. Today's question involves pieces indicative of the core of Boothby's work. This pin is made with an antique Cinese mother of pearl gaming chip. The design carved in the mother of pearl is two birds with flowers or leaves. Measures 2 3/8 inch long by 1 inch wide.
