Design classic, model MR20 tubular steel cantilever chair in gray leather, designed in 1927 by the designer and architect Ludwig Mies van der Rohe (March 1886 – August 1969) for Knoll International. Production from the second half of the 20th century / circa 1970s by Knoll International. At that time, the chairs were only marked with a sticker, not – as with today's models – with an engraving on the frame. The light gray leather has an age-related patina and gives the piece a special charm for vintage enthusiasts. Condition report: Chrome frame with signs of age and use, leather with a distinct age patina in some areas. The leather is soft and not hardened. Lacing has been renewed. Gray underneath, turquoise on the back. 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
