Chair designed by Egon Eiermann for the German manufacture Wilde & Spieth in the 1960s. The chrome steel frame has been cleaned and polished, and it is in perfect condition. Upholstery interiors replaced, upholstered with a new, high-quality black fabric. The back of the backrest is made of plastic. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
