Armchair Diamond leather of Harry Bertoia for Knoll 1970

Chair Diamond of Harry Bertoia's 1970 in leather and metal black, very nice patina. Report a micro scratch on leather. See photo, visible only with a close inspection. Its abstract and geometric design consists of a reticular structure in metal wire which is the folder as the seat as well. Bertoia's creations respond to practical criteria, but are also the result of his studies on the form, space, volume, and the witness of a manual technique of making very fine metal Bertoia was the master.
