1970s, Norwegian design. Armchair model "Kengu". Original black leather with patina, bent wood, canvas. Original good condition: no smells, no stains and stable construction. Manufactured by Norwegian furniture maker Rybo Rykken in about 1975-80s. Original Scandinavian vintage design directly from Denmark. The chair was checked by craftsman. 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
