Two very rare Thonet armchairs with original upholstering stamped. Thonet published in the Thonet catalogue 1911-1915 as nr 6506. These armchairs are not typical bentwood Thonet chairs and are often not recognized as Thonet chairs and that’s why they are very rare to find and a must for a Thonet collector. This piece has an attribution mark, I am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution
