Friso Kramer designed the ‘Ariadne’ serie for Auping in 1954. This chair is in it´s original condition and extremely rare today. Auping is a high-end Dutch bedroom manufacturer that collaborates with well-known designers. 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
