Set of 4 vintage S22 Galvanitas dining chairs stackable plywood and metal for Galvanitas 1967s

We have a stock of 4 pieces of S22 Galvanitas chairs with a mid brown plywood seating set on a black lacquered metal frame. These chairs were designed for Galvanitas in 1967. The pyramid chairs of Wim Rietveld were the main inspiration source for the folded metal frames. The frames are intact yet do have missing spots of lacquer here and there (as shown on photos), but the plywood is in very good condition. Sold as set. 46cm seat height.
