This is an authenticated vintage Eames for Herman Miller shell chair model DAH. The mocha brown color is very rare in Eames fiberglass chairs. The distinctive Herman Miller insignia is embossed on the chair’s bottom. The shock mounts, H-style base and hardware all appear to be original. The fiber grain is incredible on this timeless, iconic chair. As comfortable as it is stylish, this mid century modern armchair blends with all styles of furniture design. The latest patent on the sticker was issued in 1959, placing the probable date of production at 1959/1960. The plastic fiberglass armchair is one of the most famous designs of Charles and Ray Eames, and is still popular today.
