Swivel tulip chairs - 1960s

These come from far away & the person who entrusted them to me told me that in his country - the location of which I will not mention - buyers are unaware that the first editions from Knoll were not stamped. To this I replied to him in France too! So as you will have understood, do not look for any signature under their base or I don't know where... but I can assure you that in view of their manufacturing quality & conversation through them they are. No offense to some... A few small wears here and there or a few wrinkles which confirm the quality of the rilsan of the time. Orange colored foam, zipped cushions & original covers are in very good condition. In short, here are some of my latest finds & I prefer to sell them in sets of 4. Thank you for your understanding.
