This iconic early edition bird chair is an authentic piece from the first production series manufactured by Knoll International during the 1950s in the US. Harry Bertoia designed this revolutionary chair with its metal rod frame and a the new rilsan coating. The early models were produced with white seats and the black steel base. The chair is in an rare authentic find in very good original condition, featuring the original rubber shock mounts and screws. A beautiful collector's item ready for daily use. 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
