This very large, very impressive piece designed by Marianne Willisch features a king-size storage headboard is flanked by two large nightstands/ bookcases.
 
Willisch (Austrian, born 1897) was an important interior designer inspired by Bauhaus principals who had many significant comissions inclusing three of the 1933 "Century of Progress" World's Fair" exhibition homes and the 1965 Pritzker House.
