Book excerpt: Coveted by museum curators and private collectors alike, these striking velvety embroidered raffia cloths and ceremonial appliqu skirts were created deep in the heart of the Congo by the Kuba people. The intricate, eye-dazzling abstract designs, executed in an appealing palette of vegetal dyes, have inspired innumerable artists and designers including Paul Klee, Henry Matisse, Eduardo Chillida, Georges Braque, and Tristan Tzara. A value guide makes it an invaluable reference for collectors.
