Frank Gehry, 1972/2005 Frank Gehry is well-known for his use of unusual materials. With his 1972 furniture series "Easy Edges" he succeeds in lending an aesthetic dimension to such an everyday material as cardboard. But although they look surprisingly simple, the "Easy Edges" have been constructed with the consummate skill of an architect and are exceedingly robust and stable. Material: Corrugated cardboard, contour of layers of cardboard, edges made of natural or lacquered hardboard.
