Set of 4 classic chairs the "H-Base" designed by Charles and Ray Eames in 1961 produced by Herman Miller. All the chairs are originally marked under seating. The chairs have a Yellow fiberglass shell with an H-Base In a good condition. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
