This is the model 625 high chair 'Kids Wire Chair' by Harry Bertoia for knoll international. It is a manufacure of 1955. The children's chair is located in a beautiful vintage condition with light abrasion to painted wire rods (not coated). 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
