Pair of vintage folding chairs 1960's

Pair of folding chairs from the 1960's attributed to aldo jacober. In beautiful vintage condition, with of course some traces due to time and use (confer photos) but healthy, stable and solid. We will appreciate the sober and elegant design - geometric and ergonomic - of this model, with its thick backrest that softens its 'hollow'. In solid beech, beautiful patina of blond wood. Seat height of 45cm, backrest height of 77cm, 45, 5x37, 5 cm of impasto on the ground and 5cm thick when folded.
