yesterday's question: Claire Falkenstein.
The sculpture, owned by and on view at the New York Guggenheim, is Set Structure with Cylinders (1944), made of poplar with stain and pigmented lacquer. Last year's Pasadena Museum of California Art retrospective presented Falkenstein as a multifarious artist, but I don't recall seeing anything like this.
Solomon R. Guggenheim's art advisor Hilla Rebay judged Falkenstein a "very gifted sculptress." Peggy Guggenheim commissioned the artist to produce the doors for her Venice (Italy) house-museum.
