In a nice ploy on the gallery 's part , these clean , flat surfaces , each restricted to two colors , are shown with examples of sleek , minimal , contoured furniture by front-line designers of the period : Arne Jacobsen -LRB- Denmark -RRB- , Bruno Mathsson -LRB- Sweden -RRB- , and the Americans George Nelson , Charles and Ray Eames and Isamu Noguchi .
